Add support for LEIA target

[GotoHack]

This add support for the LEIA by H2LAB target: an open hardware and open source device targeting smart card side-channel analysis (SCA) and evaluation, for educational and evaluation purpose. It implements a fully controlled ISO7816 stack with a dedicated custom hardware platform to acquire clean measurements for SCA characterization.

Finally reviewing (oops) - we try to avoid forcing dependencies as it can break a lot of stuff. Won't accept as-is but leaving open as will rework to avoid setup.py changes.

[alex-dewar]

Will need the following changes before merging in. Additionally, I'd like to test this locally, but I run into the following issues:

[alex-dewar]

I'd like to make this optional, since smartleia does pull in a bunch of other stuff

[alex-dewar]

Also, I don't think this is available on pypi, so I'm assuming this will fail

[alex-dewar]

Same thing here (just a try except block would be fine, and log as info if the import fails)

[alex-dewar]

Same thing here - this isn't on pypi, so it needs to be removed
