fix(curve-substreams): miscellaneous fixes for balances extractions in Curve (#118)

Browse Source 
* fix(curve-substreams): filter out reverted calls in `emit_eth_deltas`

* feat(substreams-sdk): extract balances from `Deposit` events in `extract_balance_deltas_from_tx`

* ci: ignore fmt for abi files

* feat(sdk): also account for `Withdrawal` event from WETH

* chore: reorder mod.rs, remove unused import

* chore: cargo fmt
