Package proposal: magika

[emtuls]

This package is an awesome open source utility that can detect file formats much faster and better than the standard file utility that we currently use.

I think magika should be its own package and not part of the python libraries. I think the magika package should create a shortcut for it.

@Ana06 pip seems to produce an error even though everything installs correctly, causing an issue with the package saying that it installed incorrectly and will stop due to $ErrorActionPreference = 'Stop'

I attempted to copy what was done in libraries.python3.vm, but it did not work unless I changed $ErrorActionPreference = 'Continue' at the top.

Do you have any suggestions on other ways to mitigate this? If this is the only way, then I will have to add an Exclusion inside of lint.py and this will also be something that needs to be done for all future packages that install a tool via pip.

@emtuls can you use the authors from the project page? Apart from that LGTM
