[blocked] Fetch pool data from camelot about od-sdk

[jahabeebs]

Create a function to fetch liquidity details for ODG and OD. This will be used for the stats page

* [ ]  Fetch pool data from camelot https://docs.camelot.exchange/

* [ ]  Add addresses for existing pools. Later we will update the address to our own pools
  
  * a stablecoin pool for OD
  * any token pool for ODG

* [ ]  Fetch both price and liquidity data

@pi0neerpat I found two example pools to use:
Stablecoin V2 pair: https://arbiscan.io/address/0x87425d8812f44726091831a9a109f4bdc3ea34b4#readContract
Concentrated liquidity V3 pair: https://arbiscan.io/address/0x8cc8093218bcac8b1896a1eed4d925f6f6ab289f#readContract

Price data V3:

I found that we can get price data for V3 by querying globalState which returns a unint160 "price" value according to these docs: https://docs.quickswap.exchange/reference/smart-contracts/v3/pool/

Liquidity data V3:

I'm not sure about getting liquidity for V3--there's a a liquidity function but it "has no relationship to the total liquidity across all ticks" and returns a uint128 According to the analytics dashboard the current liquidity for GRAIL-USDC is 7 million https://info.camelot.exchange/pair/v3/0x8cc8093218bcac8b1896a1eed4d925f6f6ab289f but I'm not sure yet how this is related to the total liquidity in USD--I'll try to see if the SDK has this logic

Price data V2:

Seems like people usually rely on SDK methods to calculate the price because the contract itself doesn't have this as a read function like in V3--see info in getReserves (I know we aren't using quickswap but same idea): https://docs.quickswap.exchange/reference/smart-contracts/v2/pair

Liquidity data V2:

This info isn't on the contract either and will require some more research

I'm going to ask around in the Camelot Discord to get info on calculating liquidity/price data (I'm hoping their analytics app is open source but seems it's not because I couldn't find it in their GitHub)

Edit: found V2 and V3 subgraphs--will have to query these:

Focusing just on OD for now

contract systemCoinOracle.priceSource() returns UniV3Relayer 
contract UniV3Relayer.uniV3Pool() 
systemCoin.balanceOf(uniV3PoolAddress)
WETH.balanceOf(uniV3PoolAddress)
Total liquidity for the pool
WETH balance price of WETH 
OD balance = 1$
Sum (OD balance, WETH balance)
