can I disable noble getPorts if port is supplied?

Looks like you asked this on GitHub as well? https://github.com/espruino/EspruinoTools/issues/126

As I mentioned on GitHub:

You can just remove the 'noble' module, or use the --no-ble option.

getPorts needs to be called for each enabled connection type though, because the tool has to compare the port names with what's returned to figure out which port is to be connected to.
