/**
* Computes a gas estimate for a V3 swap using heuristics.
* Considers number of hops in the route, number of ticks crossed
* and the typical base cost for a swap.
*
* We get the number of ticks crossed in a swap from the QuoterV2
* contract.
*
* We compute gas estimates off-chain because
* 1/ Calling eth_estimateGas for a swaps requires the caller to have
* the full balance token being swapped, and approvals.
* 2/ Tracking gas used using a wrapper contract is not accurate with Multicall
* due to EIP-2929. We would have to make a request for every swap we wanted to estimate.
* 3/ For V2 we simulate all our swaps off-chain so have no way to track gas used.
