Python scripting broken with Python 3.9

[pmediano]

As per the title. Using the latest pre-compiled Linux release, opening or trying to run any script (either through the GUI or the command-line options) makes this error pop out:

Error: could not find symbol "PyImport_Cleanup"
Python could not be properly initialized. We must quit.

And then MRIcroGL proceeds to fail abruptly with an access violation. This is probably because PyImport_Cleanup has been removed after Python 3.8. Just to double-check, I installed Python 3.8 (via pyenv), updated the PyLib in the MRIcroGL12.ini file, and scripting works as normal again.

PS: MRIcroGL is awesome, thanks a lot for a really nice piece of software!

Thanks. This will be fixed in the upcoming release which now uses Python27-for-Lazarus.
