Some LZMA2 archives can't be read #5

Open lesderid opened 4 years ago

LZMA2 archives can do (partial) state and dictionary resets before each LZMA2 packet. This isn't yet supported because the LZMA package that is used (lzma-purejs) doesn't expose such functionality, as it's not used in LZMA1.

Due to this, all (most?) single-file LZMA2 archives can be read, but many multi-archives cannot.

This should be fixable by using LZMA.Decoder from lzma-purejs directly instead of using the decompress function. I will probably look into this in a few days.
