Caleb Gardner 7a2f9a87ba Re-wrote a bunch to try to figure out why things weren't working.

Turned out I was reading if a block was compressed exactly opposite.
Started to work more on looking up dirs.

GoSquashfs

My playground to mess around with Squashfs in Go. Might turn into an actual library someday. Mainly for AppImage

Right Now it's mostly based on distri's squashfs library

Special thanks to https://dr-emann.github.io/squashfs/ for some VERY important information in an easy to understand format

I am focusing purely on unsquashing before squashing.

Working

Reading the header
Reading data (slightly important :P)
Reading inodes
Reading directories
Basic gzip compression (Shouldn't be too hard to implement other, but for right now, this works)

Not Working (Yet). Roughly in order.

Understanding the directory table. It's a bit weird TBH.
Reading the UID, GUID, Xatt, Compression Options, Export, and Fragment tables.
Implement other compression types
Squashing

Where I'm at

Re-redid a bunch to try to make sure I wasn't durping. After that didn't work, I tried to figure out why things wheren't working, then realized HOW I was durping.
