Python packaging and wheel build

[mih]

This is WiP. Posting now to see if anything re actions integration would work. The packaging itself has been tested on linux and windows already.

@yarikoptic It is not clear to me why the patch would not apply -- it does for me locally, and it only adds files. Please advice.

Update: Applying the patch only fails on windows. The very same patch (against the same sources?) applies cleanly on macos and ubuntu.

[yarikoptic]

yep, confirming the update that it does build fine on linux and fails on windows

with error

and since that line 84 is way far after that classifiers, I wonder if without converting to windows end of lines it just failed to load/handle that file correctly? might be worth on windows trying to do some unix2dos and see how it goes... since linux seems to not care

I will push an attempt with unix2dos converted patches... will drop it if does not help

[yarikoptic]

this is confusing... it was working ok in some TEMP implementations where I had unix2dos call before applying the patches, and it worked. but now it stopped, uff... dunno ATM. Might later troubleshoot directly in github actions using https://github.com/mxschmitt/action-tmate .

At least I added installation/invocation of uv to the template/all OSes
