AssetsTools Update 10 (2.0.4)

Lot's of new features are in update 10. To name a few, 2019.3/4 assets files and bundles are supported, full bundle write support was added, AssetsView got a texture viewer (right click texture2d), and many many bugs were fixed (thanks to everyone who helped out!) There are still more things I want to add/change/cleanup before I do a full release.

Cldbs are still from 2019.2, still waiting for DerPopo to update those (if it takes too long I can do some slightly manual work to update them but would rather wait if I can)

Texture2D decoding is broken for 2019.3+ (or maybe only 2019.4?) so this will be fixed in a later update.
