Description
`Subset`s are currently only defined for `Monoid`s:
https://github.com/JetBrains/arend-lib/blob/6be71a0b2477906448d873f07277ec3289b31796/src/Algebra/Ring/Localization.ard#L23-L32
while they can be defined for `BaseSet`s. It goes without saying that this is useful in general.

Research direction
Start by reading src/Algebra/Ring/Localization.ard at lines 23-32, where Subset is currently defined for Monoids. Trace the existing BaseSet and Monoid definitions to determine the generalization boundary; done means Subset is defined for BaseSets while preserving the existing use case.
