hey this is Fábio from Balancer - very excited about brontes and looking forward to try it!

I thought about creating an issue to discuss / try to understand some things but maybe I can use this one. My first question is: doesn't brontes already have a Balancer V2 classifier for the functions you listed? 🤔 what I'm missing?

Besides, I would like to point out there are some swaps on Balancer V2 that are actually single-side add/remove liquidity - could that cause any issues? I don't see any handling for it but what happens is you have a swap where either token in or token out is the LP token itself and that probably shouldn't be classified as NormalizedSwap

Last, and very minor detail, but I think V2 pool registrations should be moved to discovery.rs? From a quick look other classifiers follow this and only Balancer is incosistent.
