Implement bracket notation for stacked pins ([1,2,3], [1-4], [1,3,5-7]).
Automatic net naming proceeds based on the smallest logical pin number
in stacked groups.
Provide explode/reform commands in symbol editor for conversion.
Supports arbitrary ranges including BGA alphanum ranges like
[AA1-AA3,CD14-CD22]
Adds some additional QA and trace logging
Fixes https://gitlab.com/kicad/code/kicad/-/issues/2004
If you have a pin with a label containing the letters "GND" in it and it
is not connected to a net with a label also containing "GND" AND there
is another pin on your symbol that _is_ connected to a net containing
"GND", then there is a likelihood that you have accidentally mixed up
your connections to the GND pin
Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
Also removes the side-effect that SCH_SHEET_LIST's
c'tor would sort the list (and write virtual page
numbers) anytime the starting sheet was the root.
Also, definitely don't build a SHEET_LIST (sorted or
otherwise) if you're not even going to use it.
Also don't build SCH_SHEET_LISTs on idle events. Better
to just always have the Next Sheet button enabled (we
already beep if you click it and there's no next sheet).
Also, use a SCREEN_LIST when you can. It's much cheaper
to create.
