feat: add skip options in checks

[affo]

This PR introduces options to skip some goroutines based on their stack.

Use case: I know something I depend on is leaking, or it is ok that something is leaking, and I want only to error on a precise leak.

Thanks for the PR @affo ! I totally get where you're coming from.

I think there's an issue with the design where the id in the stack will not necessarily be consistent across runs/machines in the way you expect it to be here, but I could be wrong.

I'll try to verify this in the next few days

@fortytw2 seems great!

Anyways I could change the option to get only the stack.
I added the id because is was available, I don't know if somebody would ever use it 🤔

[fortytw2]

If you change it to just be the stack line I think that'd be good enough @affo !

[affo]

@fortytw2 is this good to go for you or need something else?

[affo]

@fortytw2 just pinging you 😄

[fortytw2]

oh no! sorry @affo - I have an idea for this that's hard to explain but I will try to get to in the next few days, added to my todo list so I don't forget
