[Feat] Include selectTables along with skipTables

I have a very particular case, i'm getting into a legacy database, and i don't touch most of those tables, there's more than 100 tables but only use 2 or 3, and create 3 more.

Basically it makes no sense to me to write down the 100 table names in the `skipTables` property, maybe it would be better if you provide a `selectTables` that does the opposite, picks those tables to clean up.
