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.

Allow -1 in move specification to remain where we are on that
axis (#210), necessary for context-sensitive aligned output.
Add _aligned forms to printf and vprintf. Invert various output
functions so that simpler form is static inline wrapper around
more complicated form, rather than complicated form being a
static inline composition, facilitating atomic move+output. All
output forms now have a simple form (no alignment, placement at
cursor), an _aligned() form, and a _yx() form.

Implement a fairly conservative, line-granularity, two-level damage map. One on the overall notcurses object is dirtied by planar moves, creations, deletions, and resizes. One on each ncplane is dirtied by glyph output, media rendering, fades, and erasure. #83 This has some definite false positives: a hidden plane which moves will damage a bunch of lines unnecessarily. For now, don't do things like that :D.
Extra byte per line per plane, shouldn't be a problem.
Two new stats for cell elisions and emissions
Allow keypress to interrupt view-demo
ncvisual_stream() now allows a callback per frame
Allow ncvisual_open() to create its own, perfectly-sized, ncplane #128

on netcurses-demo, we're eliding about half of the total cells via this damage map. that's pretty fucking sweet! FPS increase of about 50% -- I'll take that any day of the fuckin' week, boyo. w00t!
