Opening it as a draft, because the code requires some cleanup, but still: it works.

I'm using it in my project:

The changes look in general fine but there's several different things in them besides the RAF changes. Maybe split it into different PRs so we can go incrementally?

@pedrocr Yes, there's some leftover stuff from WASM tests. I'll move it out once I got more time. Also I was trying to revive the test harness but without much success for now.

On the test harness I may have other local changes for it. And for camera support I also have some automated tooling that's not on this repo.

@naorunaoru
Add Fuji compressed RAF decoder
7f837da
Add a decoder for Fujifilm's compressed RAF format, supporting both
lossless (IS version 0x0110) and lossy (IS version 0x0010) compression.
The decoder handles the Fuji-specific interleaved block structure with
gradient-based prediction, outputting pixels at a fixed CFA phase
matching libraw/rawpy. Zero-filled sensor borders are auto-detected
and used to set correct crop values.

Add support for more X-Trans cameras

@pedrocr I've cleaned up the code. Let me know if you'd also like to exclude adding more Fuji cameras from this PR.

Opening it as a draft, because the code requires some cleanup, but still: it works.
I'm using it in my project:

The changes look in general fine but there's several different things in them besides the RAF changes. Maybe split it into different PRs so we can go incrementally?

@pedrocr Yes, there's some leftover stuff from WASM tests. I'll move it out once I got more time. Also I was trying to revive the test harness but without much success for now.

On the test harness I may have other local changes for it. And for camera support I also have some automated tooling that's not on this repo.

Add Fuji compressed RAF decoder
7f837da
Add a decoder for Fujifilm's compressed RAF format, supporting both
lossless (IS version 0x0110) and lossy (IS version 0x0010) compression.
The decoder handles the Fuji-specific interleaved block structure with
gradient-based prediction, outputting pixels at a fixed CFA phase
matching libraw/rawpy. Zero-filled sensor borders are auto-detected
and used to set correct crop values.

@pedrocr I've cleaned up the code. Let me know if you'd also like to exclude adding more Fuji cameras from this PR.
