* Align zone numbers between Editor and FancyZonesLib
Use zoneId on win+arrow

* Update tests

* Fix crash

* ZoneId starts from 0

* Define ZonesMap type

IFACEMETHOD_ macro is having trouble processing
std::map template when expanding, so return type needs
to be predefined

* Address PR comment

* Address more PR comments

* Handle .at
