Batch requests using an instantiated `Contract` object

[spacesailor24]

Currently if a user wanted to perform a batch request to interact with a Contract instance, they're have to use something similar to this:

import { Contract } from 'web3';

import { ERC20TokenAbi } from './ERC20Token';

const mainnetUSDTAddress = '0xdAC17F958D2ee523a2206206994597C13D831ec7';

(async () => {
	const erc20ContractDeployed = new Contract(ERC20TokenAbi, mainnetUSDTAddress, {
		provider: 'https://yourProvider.com',
	});

	const request1 = {
		id: 1,
		method: 'eth_call',
		params: [
			{
				to: mainnetUSDTAddress,
				data: erc20ContractDeployed.methods.name().encodeABI(),
			},
			'latest',
		],
	};
	const request2 = {
		id: 2,
		method: 'eth_call',
		params: [
			{
				to: mainnetUSDTAddress,
				data: erc20ContractDeployed.methods.symbol().encodeABI(),
			},
			'latest',
		],
	};
	const request3 = {
		id: 3,
		method: 'eth_call',
		params: [
			{
				to: mainnetUSDTAddress,
				data: erc20ContractDeployed.methods.totalSupply().encodeABI(),
			},
			'latest',
		],
	};

	const batchRequester = new erc20ContractDeployed.BatchRequest();
	batchRequester.add(request1);
	batchRequester.add(request2);
	batchRequester.add(request3);

	const response = await batchRequester.execute();
	console.log(response);
})();

Ideally there would be a more straightforward way to do this using the instantiated Contract object like so:

import { Contract } from 'web3';

import { ERC20TokenAbi } from './ERC20Token';

const mainnetUSDTAddress = '0xdAC17F958D2ee523a2206206994597C13D831ec7';

(async () => {
	const erc20ContractDeployed = new Contract(ERC20TokenAbi, mainnetUSDTAddress, {
		provider: 'https://yourProvider.com',
	});

	const batchRequester = new erc20ContractDeployed.BatchRequest();
	batchRequester.add(erc20ContractDeployed.methods.name().call())
	batchRequester.add(erc20ContractDeployed.methods.symbol().call())
	batchRequester.add(erc20ContractDeployed.methods.totalSupply().call())

	const response = await batchRequester.execute();
	console.log(response);
})();

Keep in mind that we'd have to append .call() or .send() to each batch request to distinguish whether we should use eth_call or eth_sendTransaction - I suspect implementing this will not be super straightforward, but it's necessary

after team discussions decided to add functions which generates right object
erc20ContractDeployed.methods.name().generateRawCall()

erc20ContractDeployed.methods.name().generateRawSend()
