this is a small jetstream-consuming server that can notify
subscribers of when a repost of theirs has been liked.

right now it will fetch your follows and listen to those
users for likes. this will be made more configurable later

also right now since it only uses one jetstream websocket
for listening to likes and no more it cannot handle more
than 10k total followed users, this is due to jetstream WS
max DID filter count limit. this will be fixed aswell

### usage

get go, build it, run it.

open a websocket at path `/subscribe/:did` where `did` is
your DID (or any other user you want to stalk.)
