[Suggestion]: Add settings to change Medium and Large field sizes

[SpiderTash]

For those that prefer very large fields, could you add some settings into the settings menu to change at what sizes the game changes up to Medium and Large sizes?

I know the code to hard code it into the main.lua file is below:
-- Increase the MED and LRG field sizes
AbstractFieldMission.FIELD_SIZE_MEDIUM = 6
AbstractFieldMission.FIELD_SIZE_LARGE = 20

I tried to make a lot more simplistic contract mod that the only settings were the number of contracts, active contracts, and this, but I can't even make it close enough to setting up in-game menus. Trying from scratch I just kill the game if I try and go any farther than a hard missionVehicle.xml overwrite.
Thank you
