* Implement warning diagnostic flags for RGBFIX
* `-m/--mbc-type help` prints to stdout
* Support `-m list` as well as `-m help`
* Make invalid `rgbfix -l` characters a fatal error, like other invalid CLI arguments
* Refactor fix/main.cpp into multiple files
It's unlikely that a specific value matters, though in theory possible;
however, an exhaustive test every time is really slow, and testing a couple
random values should, over time, cover everything.
It is fine to test random values because those tested will be logged,
so the problem can be manually reproduced later.
It does make CI technically not deterministic... but that should be fine.
* Fix compatibility of rgblink -O and -t
The -t "tiny mode" option makes ROM0 cover 0x8000 bytes,
not 0x4000. The -O "overlay" option fills areas uncovered
by sections with data from an overlay file. These needed
to cooperate so that the calculated uncovered overlay size
does not exceed the actual size of the ROM.
Fixes#754
* Print link test names like asm tests do
* Make the three test.sh scripts more similar
- Make it work inside pipelines
- Add RGBFIX tests to the suite
- Be more flexible in accepted MBC names
- Add warnings for dangerous or nonsensical input params
- Improve man page
