Rangi a2c52caca2 Disallow NUL characters in section names and assertion messages 
Allowing these in object files would lose anything after the '\0'
when RGBLINK reads the object.

Rangi 0c772ea049 Update external testing CI with libbet's new way of running Python 
libbet now uses `py -3` if the `py` binary exists, instead of if
`COMSPEC` is defined. So we don't need to `unset COMSPEC`, we just
need to avoid Windows' `py` launcher from being in Cygwin's `PATH`.

It turns out that `C:\cygwin\bin\env.exe CYGWIN_NOWINPATH=1 ...`
was not effectively preventing Windows' `PATH` from being inherited
by Cygwin's `PATH`, because to take effect it needs to run Cygwin's
`/etc/profile` script. The simple way to do that is using a login
shell. So we don't need the `PREFIX`/`--prefix` from the previous
commit after all.

Rangi 80c8e77b19 Fixed-point FMOD and LOG explicitly return 0 for some invalid inputs 
This is consistent with `fix_Div`'s explicit error handling,
and does not rely on subtle C/C++ `fmod` or `log` IEEE 754 behavior.

Rangi b0948566bb Fail-safe treat 16-bit alignment as a fixed address even in RGBLINK 
RGBASM does this itself, so should not output sections with 16-bit
alignment, but an invalid object file could otherwise cause
`getPlacement` to infinitely loop.

Rangi 5869e0dc60 Fix RGBLINK scrambling algorithm to work for SRAM 
Since SRAM sections start from 0, we had been using a signed
`int8_t curScrambleSRAM` counter to allow 0 as a scrambled bank,
but this actually just placed all floating SRAM sections in bank 0.

Rangi 8b951bc047 Fix a flaky/random-seed rgbgfx_test test failure 
Commit 21eaa2d2cc missed some
intentional unsigned underflow that is needed to set `nbTilesInBank`.
Without it, some of the randomly-seeded RGBGFX tests, such as
`./rgbgfx_test seed8.bin -b 207 -N 54,256`, can fail with "Color
mismatch after round-tripping" errors.

Rangi 3b33c942ae Fix a crash and a limitation in RGBGFX unoptimized output 
- If both banks 0 and 1 were completely filled, then
  `assume(bank == 0)` would false and potentially crash.
- If the input image had fully-background tiles, they would be
  incorrectly counted towards `nbTiles` and could cause the
  "Image contains N tiles, exceeding the limit" check to fail.

Rangi 7b39bcd412 Refactor expression for clarity 
`tileData[realY + 1 % options.bitDepth]` relied on order of
operations and the fact that `1 % 1 == 0` but `1 % 2 == 1` for
correct indexing. However, it was not obvious at first glance,
and confusable with the more common `(base + offset) % size`
pattern. (And would need changing anyway if we ever support 4bpp.)
