Add windows compatibility

[po09i]

Description

This PR add windows compatibility to the toolbox

In more details:

• Adds a .bat script to install Shimming Toolbox
• Make modifications to ensure "all" features work (All tests are passing except prelude and sct tests since I have not installed them)
• Solve unwrapper issue (We only natively support prelude which seems to only be installable on linux/Macs, Implement skimage's phase unwrapper #473 implemented skimage so we have an unwrapper installed)
• Add windows installation section

A future PR should add windows installation and testing in the CI

st_b0shim dynamic works well. Create field maps doesn't work and I couldn't do the create coil profiles tutorial because of the bash commands

Thanks for testing it out!

I believe prelude does is not available on windows (FSL recommends installing it through WSL). Therefore I would not expect it to work, is that the error message you get? Good point about the tutorial, they will need to be updated.
