window executable with embedabble python results huge file

• how to setup to remove the no needed files?

According to #96, it seems like there is nothing left to reduce here, correct?

(Once #68 is merged, where only relevant TOPP tools and all dll dependencies are copied)

looking at our OpenMS Windows installer there are native Windows DLLs in there like shell32.dll. Reading up on it, we should not actually do that (its not allowed!) - see https://stackoverflow.com/questions/68345233/which-dlls-to-include-with-my-compiled-executable-distinguish-between-system-a

Bottom line: we need a manual list of dll's that we curate (luckily our dependencies do not change that often), but it's some effort initially and we'd need to test this on a fresh Windows VM which is as vanilla as possible to make sure we did not forget anything.
On the bright side: the installer size will reduce considerably.

Interesting. Shell32 should indeed not be there.
Here we tried to exclude some with patterns: https://github.com/OpenMS/OpenMS/blob/decb5c832cbf4e8fc85583fb6e44375150cdb3d4/cmake/package_general.cmake#L72

Feel free to try to adapt. Also depends a bit on the machine where it is built on. These days GHA runner.
