Benchmark encoding/decoding speed and compare with other implementations

Encoder/Decoder protocols for Map override protocols for other structs. So it's not possible to define custom encoding/decoding logic

hi there, thanks for your good work.

when i send transaction using Ethereumex.HttpClient.eth_send_raw_transaction(signed_transaction), sometime errors occur just like that:

no match of right hand side value: {:error, %{"code" => -32000, "message" => "rlp: non-canonical integer (leading zero bytes) for *big.Int, decoding into (types.Transaction)(types.txdata).R"}}

ex_rlp version: the latest version 0.5.3

if i change any part of transaction, nonce, gas_price, etc., errors disappear.

i searched for a long time, it looks like a problem of RLP, mentioned years before:

https://ethereum.stackexchange.com/questions/71616/ethereum-boardcast-shows-error-non-canonical-integer-leading-zero-bytes-for

MOACChain/moac-core#24

it looks like that's hard to reproduce it, cause it's random to generate the leading zeros in R or S. i will try it more using large amount of random transaction arguments, as this error reproduced, it will be posted here.

thanks in advance.

"what the fuck" |> ExRLP.encode(encoding: :hex) 
"8d7768617420746865206675636b"

Decode It in Web3.js：

 web3.utils.toAscii("0x8d7768617420746865206675636b")
'�what the fuck'

There is an extra symbol there

Currently, we don't handle errors from https://github.com/ethereum/tests/blame/develop/RLPTests/invalidRLPTest.json
