Update swap aggregator (frontend quote) integrations

[SamusElderg]

Currently 1inch etc must be using some complex logic to calculate swap estimated outputs for their frontend/api for SPv2 pools, now that we have an easy swapQuote endpoint we should reach out and make this easier for them

Endpoint details below 👇

/v1/swapQuote?inputAddr=0x...&outputAddr=0x...&inputUnits=100000000000000000000

Returns estimated swap output for swapping InputToken * InputUnits -> OutputToken via SpartanProtocol V2 AMM.
inputUnits type is WEI (not units). So if you want to swap 1.00 BNB/unit you would enter 1000000000000000000.
The return amount is also in WEI as a string, so interfaces will need to convert from WEI -> units for users.
When swapping to/from BNB you can enter either the WBNB address (0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c) or the BNB address (0x0000000000000000000000000000000000000000) the API will convert both to the corresponding correct WBNB pool.
