[Feature]: include prior mapID in onChangeMap

[Jmr3366]

Describe the Problem

With the new onChangeMap event, it passes through macro.args the mapID of the map you're going to, the destination.
I'd like to compare the from map and to map via macro.script to perform different actions.

The Solution you'd like

Include as a second string list entry in onChangeMap the from mapID

Alternatives that you've considered.

Tracking all the maps and tokens on the maps and doing compares to figure out where the token came from.
