feat: Add openPortByName methods for input and output ports

[MarquisdeGeek]

Provide a name-oriented way to open ports, rather than an index, since the MIDI index is want to change.

You may have issues with this code, in the event that there are 2 devices with the same name. In my code, a number is added to the name if there is more than one. e.g. Uno-MIDI-1, Uno-MIDI-2 etc. (Not my idea, I think that was in the original code)

I was pondering something similar - should/could openPortByName happen in two passes: first, check for an exact match, and secondly for an name.includes match?

In my case, I just scan for all the names when opening and make a list of the names and match them with the id, then when doing the actual open, match the name and use the matching id. (again, not my idea, but it seems to work well)
