[File] [PATCH] games: Add Panda3D game engine formats

[Derzsi Daniel]

This patch adds support for two binary Panda3D game engine formats. One of them is the BAM format, which is used to represent 3D models inside the Panda3D game engine. The other is the MF format, which is a game archive that can hold game assets similar to a ZIP file.

Both formats are documented on the internet. Test files for Panda3D multifiles can be found at https://github.com/toonjoey/toontown-project-bikehorn, while test files for Panda3D BAM files can be found at https://github.com/Toontown-Open-Source-Initiative/Toontown-School-House/tree/master/resources/phase_3.5/models/gui.
