squashfs (WIP)

A PURE Go library to read and write squashfs.

Currently has support for reading squashfs files and extracting files and folders. Supports all compression types except LZO, but additional compression options are hit or miss.

The only major thing missing from squashfs reading is Xattr parsing.

Special thanks to https://dr-emann.github.io/squashfs/ for some VERY important information in an easy to understand format. Thanks also to distri's squashfs library as I referenced it to figure some things out (and double check others).

Performane

This library, decompressing the firefox AppImage and using go tests, takes about twice as long as unsquashfs on my quad core laptop. (~1 second with the libarary and about half a second with unsquashfs)
