Small bugfixes, custom folders export, script templates

This new release adds the following

1. You can define output folders for all things now when invoking the builder:
   • groundTruthDirectory(java.io.File groundTruthDirectory) Specify the training directory where thes test and train images will be added
   • tempDirectory(java.io.File groundTruthDirectory) Specify the temporary directory when using cellpose inference
   • modelDirectory(java.io.File groundTruthDirectory) Specify the where the model will be saved
   • the Quality Control results remain inside the model directory
2. an Omnipose internal variable name had a typo and was fixed. You will have to re-enter the path in in your Edit > Preferences if you are using Omnipose
3. Script templates: Training and detection script templates are now in Extensions > Cellpose, Just like the StarDist extension (Thank you @petebankhead)
4. Names for Cellpose preferences were changed to empahsise how we need the full path to python.exe

Happy Cellposing
