How to use auto permit(allowance) when operating the position?

[leyafo]

Hi, guys. Thanks for sharing this SDK.

I have a question about auto perimting allowance when calling mutilcall. I saw two parameters (Token0Permit, Token1Permit) in CommonAddLiquidityOptions:

//  Options for producing the calldata to add liquidity
type CommonAddLiquidityOptions struct {
	SlippageTolerance *core.Percent  // How much the pool price is allowed to move
	Deadline          *big.Int       // When the transaction expires, in epoch seconds
	UseNative         *core.Ether    // Whether to spend ether. If true, one of the pool tokens must be WETH, by default false
	Token0Permit      *PermitOptions // The optional permit parameters for spending token0
	Token1Permit      *PermitOptions // The optional permit parameters for spending token1
}

These two permit parameters defined in https://github.com/daoleno/uniswapv3-sdk/blob/master/periphery/selfpermit.go

I know it would be wrapped in AddCallParameters automatically. But I don't know how to wrap the VRS(signature data).
Can you give me a simple example for calling AddCallParameters with perimited parameters?

I haven't used these features, so can not help you. But I advice you to take a look at official js version of uniswap v3 sdk, I assume this sdk follows the same logic.

Same as @Vaulverin . And thanks for your examples. If you have this part of the sample code, feel free to contribute it.
