Support Multi paths (eg: USDC-> BNB ->UNI)

[makoto]

Description

It currently only supports a few stable coin swaps mainly because other swaps do not have direct pairs.

Ideally, it should make use of besttradeexactin function provided by Uniswap SDK but there are 2 challenges doing so.

• sdk has the router address hardcoded
• to derive the best path, you have to pass each available pairs as done in uniswap-interface code

Option 1 (Preferred)

Make a separate library that simplifies the function call to derive the best path. Ideally, I would like to have the function as easy as 1inch quote-swap API (The reason I just don't use their API is that they currently only support L1 and BSC. I would like to have platform-agnostic tool).

Option2 (Less preferred)

Make use of the existing fork SDK of each uniswap clones to derive the best path.
