Creates a new pool if it does not exist, then initializes if not initialized
Note：
This method can be bundled with others via IMulticall for the first action (e.g. mint) performed against a pool.
Parameter：
token0：The contract address of token0 of the pool.
token1：The contract address of token1 of the pool.
fee：The fee amount of the v3 pool for the specified token pair.
sqrtPriceX96：The initial square root price of the pool as a Q64.96 value.
Return：
pool：Returns the pool address based on the pair of tokens and fee, will return the newly created pool address if necessar
2. Mint （Contract: NonfungiblePositionManager）
Creates a new position wrapped in a NFT. ( Adds liquidity )
Note :
Call this when the pool does exist and is initialized. Note that if the pool is created but not initialized a method does not exist, i.e. the pool is assumed to be initialized.
Parameter :
struct INonfungiblePositionManager.MintParams：The params necessary to mint a position, encoded as
MintParamsin calldata.
Return :
tokenId：The ID of the token that represents the minted position.
liquidity：The amount of liquidity for this position.
amount0：The amount of token0.
amount1：The amount of token1.
3. getPool (Contract: UniswapV3Factory )
Use the getPool function in the FACTORY contract to check if a pool already exists.
Parameter：
tokenA：The contract address of either token0 or token1.
tokenB：The contract address of the other token.
fee：The fee collected upon every swap in the pool, denominated in hundredths of a bip.
Return：
pool：The pool address.
4. decreaseLiquidity（Contract: NonfungiblePositionManager）
Decreases the amount of liquidity in a position and accounts it to the position (remove Liquidity)
Parameter：
struct INonfungiblePositionManager.DecreaseLiquidityParams : tokenId The ID of the token for which liquidity is being decreased,
Return：
amount0：The amount of token0 accounted to the position's tokens owed.
amount1：The amount of token0 accounted to the position's tokens owed.

Throws if the token ID is not valid.
Parameter：
tokenId：The ID of the token that represents the position.
Return：
nonce：The nonce for permits.
operator：The address that is approved for spending.
token0：The address of the token0 for a specific pool.
token1：The address of the token1 for a specific pool.
fee：The fee associated with the pool.
tickLower：The lower end of the tick range for the position.
tickUpper：The higher end of the tick range for the position.
liquidity：The liquidity of the position.
feeGrowthInside0LastX128：The fee growth of token0 as of the last action on the individual position.
feeGrowthInside1LastX128：The fee growth of token1 as of the last action on the individual position.
tokensOwed0：The uncollected amount of token0 owed to the position as of the last computation.
tokensOwed1：The uncollected amount of token1 owed to the position as of the last computation
