made a GetFollows, and made the GetFollowers and GetFollowing use that (and also removed GetAllFollows since its not necessary with GetFollows)

this is pretty cool! couple of points:
- the
GetFollow*methods are a bit repetitive (in part due to thedatabase/sqlAPIs), can we dedup them like we do in the rest of the codebase? the approach we use here is to writeGetItem(e Execer, filters ...filter) ([]Item, error)and then use filters to create more specific getters. you can look atdb/spindlesfor an example - we could do something similar for
GetFollowStatusi think
oops T.T actually fixed it
