Error when installing through Blender's UI

[gentlegiantJGC]

The folder name inside the zip source includes the version number which makes the folder an invalid python id when blender tries to import it.

Steps to reproduce

1. Open Blender's addon menu
2. Click install
3. Select the downloaded zip file
4. Click the check box to enable the addon
5. See the error in the console

Traceback (most recent call last):
  File "D:\Programs\Blender\2.90.1\2.90\scripts\modules\addon_utils.py", line 351, in enable
    mod = __import__(module_name)
ModuleNotFoundError: No module named 'tree-gen-0'

The folder in that path is actually tree-gen-0.0.3 which is the same as in the original zip file.
The solution is probably to create a github workflow to build the install file correctly

Yeah, it's a packaging issue. For others visiting with the same problem, here's a file that works.

I've updated the 0.0.3 release, annoying that we can't use the automatic github packaging for this any more
