@mdsteele hello! thank you for the great library! I have cab archive (get from MSI): python.zip

I have two problems:

  1. Unpacking is very slow
  2. A lot errors: 
    w9xpopen.exe unpacker error=Custom { kind: Other, error: ChunkTooLong }
README.txt unpacker error=Custom { kind: Other, error: ChunkTooLong }
NEWS.txt unpacker error=Custom { kind: Other, error: OverreadBlock }
LICENSE.txt unpacker error=Custom { kind: Other, error: InvalidBlock(0) }
python.exe unpacker error=Custom { kind: Other, error: ChunkTooLong }
pythonw.exe unpacker error=Custom { kind: Other, error: ChunkTooLong }
python27.dll unpacker error=Custom { kind: Other, error: OverreadBlock }
...

Thanks. It looks like that CAB file is using Lzx(21) compression, and those errors seem to be coming from the lzxd crate (see https://github.com/Lonami/lzxd/blob/ba70d7f8292ce840267b1ab89d44a9685c72ba1f/src/lib.rs#L90). The cab crate is already using the latest available version of lzxd (v0.1.4). So probably you'll need to report these issues there, sorry.
