mapluisch/TripoSR-for-Unity

Added text2texture generation by ejones. Also, added a large `.unitypackage` ("with.packages), which bundles the python soure code for TripoSR and triposr-texture-gen, so that you don't have to clone it yourself.

Initial release as installable `unitypackage`. This package does not contain TripoSR - please be sure to follow the setup instructions in my README.
