Add SC5511B driver

[ttshaw1]

Added driver for SignalCore SC5511B. Plenty of room for optimizations and new features but might be enough to get some other group up and running.

@ttshaw1 could you have a look at these typing errors https://github.com/QCoDeS/Qcodes_contrib_drivers/runs/7405036031?check_suite_focus=true ? if haven't worked with python typing and mypy before, we can do one of the following: exclude this driver from type checking alltogether, add # type: ignore to all the troubling lines, remove existing partial type annotations. I don't recommend either of these, but we have to be realistic and do what we can.

@ttshaw1 is there still interest in this driver? It would need a bit of work to get the CI to pass
