Build a scoop manifest file for Mathics

[SiyuChern]

Could you please build a scoop manifest file for this project, such that we can easily install Mathics? (see ScoopInstaller/Extras#6847 (comment))

Feel free to put in a PR.

Wouldn't you install this with pip rather than with scoop? (first install python with scoop, then use venv to use pip to install mathics?)

Update: Nevermind, it turns out to install this with pip, you need visual studio to compile nlp processing packages :(
