PS2 Stargazer - Extract PSX STAR files

[Brawl]

Stargazer is a tool developed by me which can extract "STAR" files from the PSX which are used by its package manager.

It's developed in Go and hence cross-plattform.

• Download binaries on GitHub
• Find the source code on GitHub (released into the Public Domain)

To use it, either drag your ".star" file onto the binary or use the command line:

stargazer <file> [output dir (optional)]

If no output directory is given, the file is extracted to the file name minus the extension plus "_extracted" (e.g. xPackmanJr_0.105.star -> xPackmanJr_0.105_extracted).

I have also added experimental packing in an extra branch and created an issue to keep track of it.
