Resolves#410. notcurses_at_yx() accepted a cell*, but the
gcluster of this cell was always set to 0. The EGC is instead
a heap-allocated copy, returned as the primary return value.
This is due to the absence of an egcpool to bind against.
Existing callers can be converted thus:
* instead of passing cell 'c', pass &(c)->attrword, &(c)->channels
* either initialize 'c' with CELL_TRIVIAL_INITIALIZER, or set its
gcluster field to 0 following the call
I've updated all calls from tests/demos, updated the docs, and
updated the C++ and Python wrappers.
Add ncplane_bound(3). This allows a new plane N to be created in the
*bound* state relative to another ncplane B. If B moves, N moves the
same amount. If N is moved, the coordinates are taken relative to B
as opposed to the standard plane. If B is destroyed, N is destroyed.
Each plane can have many planes bound to it, but can only be bound to
a single plane. Add ncplane_reparent(3). This allows a plane to be
detached from any plane to which it is bound, and optionally rebound
to a new plane. The standard plane cannot be reparented.
Documentation and unit tests have been added for both.

ncplane_mergedown() is similar to the "Merge down" operation
in the GIMP. It writes to the destination plane the result
of rendering the source and destination frames per se.
Add four new fields to notcurses_options: margin_{tblr}, which requests margins to the top, right, bottom, and left. Render only within those margins, leaving the screen otherwise untouched (well, cleared if using the alternate screen). #293

Get rid of annoying empty line in notcurses-view (and ncvisuals at offsets in general)
Implement most of the Selector widget. Need to add styling and scrolling still. #166
Reenable ubuntu focal build
Subtitles! We decode them, and display them in notcurses-view. If ncvisual_simple_streamer() is provided an extra ncplane, it will use it to display subtitles. #95
We now build Python by default, as things are working much better.
ncplane_set_base() now takes channel, attrword, and EGC, so you can usually avoid having to set up and release a cell. ncplane_set_base_cell() takes over duty from ncplane_set_base() for ease of conversion.
notcurses-demo and notcurses-view now both accept a 0 for delay multiplier, meaning 'go as fast as you possibly can'. Very small multipliers (e.g. 0.00001) no longer cause floating point exceptions.
fading routines no longer cause floating point exceptions on very small timescales.
Introduce the new type 'ncdirect', a stripped-down 'notcurses'
suitable for inline modification of regular output. Used the new
type because otherwise there were going to be if(directmode) checks
everywhere. Direct mode encompasses only colorizing and styling.
Add new man page notcurses_directmode(3). Add new section to README.
Add new PoC using direct mode RGB. Update demo table summary to use
direct mode.
As it turns out, we can't portably load the initial terminal contents
(there are some hacks of various EXTREME nature, but none of them are
worth it for the rather limited benefit). The O(1)-time damage
inference requires knowledge of what was previously present to
inibit unnecessary draws. We would then need some special cell value
indicating "not yet written to" to distinguish a purposeful null
cell from an initial cell. Again, we could do this, but for what value?
Finally, the idea of clearing new area on SIGWINCH was always flawed,
as we can't do that from a signal handler.
With the advent of direct mode #77, the reason for this largely goes
away in any case.

Request and parse up mouse messages. We handle up to 11 mouse
buttons, 3 modifiers (currently thrown away), motion while
holding down a button, and loss/gain of focus. I've added twelve
new NCKEYs: one for each button, and one for release. In addition,
I've introduced the 'ncinput' struct, which encodes the nckey plus
extra data. The only extra data thus far is coordinates for mouse
events. It is not necessary to provide a ncinput to all input
functions; NULL can be provided if the caller doesn't care about
details. All demos are updated. notcurses-input has been updated
to decode full information of returned ncinputs.
The primary resource for this work was Dickey at al's "XTerm Control
Sequences", https://invisible-island.net/xterm/ctlseqs/ctlseqs.html.

While ncurses 6.1 adds the `RGB` capability to terminfo, the flag is not
commonly used in terminfo entries as of now. The `COLORTERM` environment
variable is, otoh, commonly present and set to either `truecolor` or
`24bit` value by terminal emulators which support direct color.
Add a check for this if `RGB` is false (or absent)
With this check in I was able to properly appreciate the awesomeness of
notcurses demos :)
