* Minor fixes
It turns out setting a map value with the index notation causes
an lookup that can be avoided with emplace. Apply this to one line in
the StoreForward module.
Fix also Cppcheck-determined highly minor performance increase by
passing gpiochipname as a const reference :)
The amount of cycles used on this laptop while learning about these
callouts from cppcheck is unlikely to ever be more than the cycles
saved by the fixes ;)
* Update PortduinoGlue.cpp
