CCID: Support for Get and Set Parameters

[kidbomb]

This push request add support for 2 USB CCID messages:

• GetParameters
• SetParameters

The CCID layer is already mature at this point, so as far as applications are concerned, I believe we could merge it to the main branch now. However, I still intend to add some basic support for ISO7816 into the demos, and that could take a while. I plan to do this incrementally, and I already have some basic functionality at place, which I will create a pull request for as soon as this first PR got approval.

Looks good, just some minor formatting that I'll fix up. Let's get this merged and cleaned and then we can do final merge checks before shoving it in master.

Ok, did a little cleanup. Last round I think - double check the branch state and I'll create the final merge request.

The branch looks good - I'll double check today by running the tests and as soon as it is done I'll let you know.

Tests looks good - let's merge it to master then!
