Bump version to 3.0.1 release

Fix T95099: Have launcher wait for Blender exit
unity launches blender in background mode to do some file conversions, ever since the launcher got introduced this process broke. The root cause here is: Unity looks up the default program to launch .blend files with, which is now the launcher, then launches it in background mode with a script to export the data. The launcher however was designed to exit as quickly as possible so there would not be an extra background process lingering. It does not wait for blender to exit and does not pass back any error codes. This broke unity's workflow since it assumed if the process exits and succeeds the data *must* be ready for reading which no longer holds true. This change keeps the launcher design as was previously, *except* when launching in background mode, then it waits and passes back any error codes, thus restoring unity's workflow.
