add block-specific collector using tycho client

[itamarreif]

this will make end-to-end testing much easier

i think this will work for a univ2 pool:

1. use tycho-client's get_protocol_states to get a ProtocolStateRequestResponse, which contains a vector of ResponseProtocolState
2. use the ProtocolSim implementor's try_from_with_block and cpmm_try_from_with_block to decode the response into a UniswapV2State

this will make #25 easier to implement since we can run it on a specific block instead of "until we find a signal"
