Split Codebase

[samcorky]

For v2.0 of SMIB (or earlier), I think we should split out the SMIBHID code into its own repo.

This guide can be followed to migrate a directory to a different repository whilst retaining commit history.

Think this would make both code bases cleaner and make testing easier.

As smibhid seems to be quickly growing, I think this makes sense to be done sooner rather than later. Last couple versions haven't had many SMIB changes, almost all SMIBHID.
