Add option for Generated Fields to be stored in number format (integer or float)

[thupsi]

There was a case described in Discord where having the option to store Generated Fields in number format would prove beneficial, specificaly for sorting puproses.

This would also help if when Generated Fields are available as columns in element indexes (wink wink, nudge nudge)! 😉

I’ve definitely thought it’d be nice if we could store more than just strings too 👍
