Probably won't have a chance to look at this for awhile. Feel free to make a PR!

Quick update from an actively maintained fork:

• release: https://github.com/Huh-David/bmp-js/releases/tag/v0.5.0
• package: https://www.npmjs.com/package/@huh-david/bmp-js

This release closes the encode bit-depth parity gap and now supports BMP output bit depths:

• 1, 4, 8, 16, 24, 32

Plus:

• palette-based encoding for 1/4/8-bit modes
• expanded regression coverage (header/padding/roundtrip/failure cases)

Implementation PR:

• feat(encode): add multi-bit-depth output parity Huh-David/bmp-js#13

If upstream resumes maintenance, I can help provide a focused backportable patch.
