Add GitHub Workflow to generate transferwee.exe

[sharevb]

Add GitHub Workflow to generate transferwee.exe in onefile mode. This will allow a more simple use on Windows than installing python, etc...

Sorry but I would not like to build and redistribute binaries and maintain that for Windows.

I should try to investigate about pip and pushing it there (more or less it is the defacto standard and then people can more easily use it from that).

Thank you @sharevb!

Hi @iamleot, no problem. Actually, I use your tool as a standalone exe because it is really easy to deploy on windows as it is just by copying without having to install python and so on...You know Windows devs are lazy ;)
I will do a fork to provided this PR as myself in another repo and maintain it myself from you updates here. May you then could just provide a link to my incoming repository ? may be also to provide a linux build also
