abigen generated bindings can be optimized by parsing abi once during an init function

[trinhdn2]

We are working with multiple bound contracts which are serving the consensus and exclusive services like TomoX/TomoZ. Let's take the BlockSigner contract for example, this bindBlockSigner function is called each time the validator want to make a call or an transaction to this contract at 0x0000000000000000000000000000000000000089

package contract

// bindBlockSigner binds a generic wrapper to an already deployed contract.
func bindBlockSigner(address common.Address, caller bind.ContractCaller, transactor bind.ContractTransactor, filterer bind.ContractFilterer) (*bind.BoundContract, error) {
	parsed, err := abi.JSON(strings.NewReader(BlockSignerABI))
	if err != nil {
		return nil, err
	}
	return bind.NewBoundContract(address, parsed, caller, transactor, filterer), nil
}

To prevent re-initializing the ABI each time. we can move the parsed abi.ABI to an init function of the contract package.
