Add cash_in=* to amenity=atm

[pos513]

Key cash_in=* allows to specify whether amenity=atm allows depositing of cash.

Documentation: ​osmwiki:Key:cash_in
As of today (2023-08-09), there are more than 20k ATMs with this key: ​https://taginfo.openstreetmap.org/keys/cash_in

Maybe also a checkbox for cash_in:coins=* could be considered, but as least in my part of the world, ATMs accepting coins are rare.
