* feat: add uniswap-v4 mainnet yaml

* fix(uniswap-v4): miscellaneous fixes for UniswapV4 (#147)

* fix(uniswap-v4): correctly decode swap event deltas.

Deltas are given from a user debt perspective by the event (negative if received by the pool, positive if sent by the pool). In our usecase we need the opposite of this. This commit uses `.neg()` on the amount to apply them correctly.

* fix(uniswap-v4): correctly compute token amounts.

We were using `get_sqrt_ratio_at_tick` at the current tick to compute the amounts. This was incorrect because it provides the price at the tick boundary, but we might be mid-tick, which could lead to erroneous balances.

We now track the current price (updated by `initialization` and `swap` events) and use it when calculating the amounts.

* fix(uniswapv4): do not account for fees in swaps.

Previously we were adding fees as balances. But they are actually not part of the TVL and we aren't accounting for fees in the position changes (withdrawals). This commit addresses this and remove the fees from the token balances.

* refactor: fix pb mod.rs

* refactor: bump version and update sepolia config

* ci: make clippy happy

* refactor: clean unimath tests

* refactor: make logic clearer and improve docstrings
