Unexpected web3::contract::tokens::Tokenize is not implemented error

Hi,

When I compiled my code which contains a smart contract invocation, I got a following error.

error[E0277]: the trait bound `([web3::types::H160; 3], [web3::types::U128; 8], [web3::types::U256; 6], [web3::types::H256; 5], std::string::String): web3::contract::tokens::Tokenize` is not satisfied

   = help: the following implementations were found:

For more information about this error, try `rustc --explain E0277`.
error: could not compile `relayer`.

To learn more, run the command again with --verbose.

However, when I change ary3 length from 6 to 8, the compile went well.
Does the array length affect to the compile result?

Thank you

Yeah, unfortunately Rust requires us to implement this trait manually for every size and it was only implemented for 5 and then 8 and 16. I've added implementations for up to 16 elements and then power of two in #307
