[CGMZ] Core - Version 1.41.0

Hi all, today this plugin was updated to version 1.41.0!
This version adds some listeners for print commands, which can help [CGMZ] plugins behave correctly in case the game screen is printed. This might include things like hiding cursor, etc. This update also added a utility function to parse rectangle json objects.
