XZ: Unknown filter id 7

[wcampbell0x2a]

Trying to move my library to using this rust implementation, but running into some issues with decompressing some images. I added a print of the bytes for your help if you wish to fix this issue. It might be something non-standard with these pieces of firmware.

This filter is not yet implemented. For the moment, only the LZMA2 filter is implemented within the XZ container format: https://github.com/gendx/lzma-rs/blob/v0.3.0/src/decode/xz.rs#L173-L183.

Looking at the tukaani project, this appears to be a filter specific to ARM: https://github.com/tukaani-project/xz/blob/v5.4/src/liblzma/api/lzma/bcj.h#L41.
