[BUG] OptimalSwap cannot handle pool with very small liquidity

[bigbangbtc]

Giving the case:
At block number 121687748 in optimism network,
the pool 0x3C01ec09D15D5450FC702DC4353b17Cd2978d8a5 (usdc/susd) of velodrome (a fork of uni v3)
has a small liquidity: 11642027136319108.
The amounts account for the liquidity are:

• amount0: 8479 usdc (decimal 6)
• amount1: 575729140021818823 susd(decimal 18)

If I try to add 204503157101251919 susd to the pool, the optimal swap will return 0 amount to swap.

I believe it's the precision cause the problem.
as USDC has 6 decimal, while SUSD has 18 decimals.
