Consistent encoding/decoding of the parameters

[nazarhussain]

Is there an existing issue for this?

Feature Request

Currently the web3-eth-abi package have to functions encodeParameters and decodeParameters. Both of these works fine but don't have a consistent output.

1. We can't use the output of one function to pass to other
2. Decoding result in different format of data used to encode

Use Cases

The following code snippet should work fine.

const abi = ['uint256', 'string'];
const inputParams = ['2345675643', 'Hello!%'];

const encodedOutput = encodeParameters(abi, inputParams);
const decodedParams = decodeParameters(abi, encodedOutput);

assert(inputParams === decodedParams);

Implementation Ideas

The reason behind the difference is the implementation of the output format. Which is not based on array index rather object index. Same behaviour exists in 1.x and 4.x
