[C++] API sync

Added:
 * Cell: get_addrword (`cell.attrword`)
 * Cell: get_channels (`cell.channels`)
 * NotCurses: get_stdplane overloads (`notcurses_stddim_yx`)
 * Plane: putc (support for `ncplane_putsimple_stainable`,
   `ncplane_putegc_stainable`, `ncplane_putwegc_stainable`)
 * Plane: format (`ncplane_format`)
 * Plane: stain (`ncplane_stain`)
 * Plane: translate (`ncplane_translate`)
