We should prohibit denoms longer than 255.

Can i have any reason for 255 limit?

It's because our newly introduced lengthPrefix() assumes it (converts length to byte).

It's because our newly introduced lengthPrefix() assumes it (converts int to byte).

Thanks for letting me know.

I found regex for denom validation [a-zA-Z][a-zA-Z0-9/-]{2,127}. function to get key will be called after validation logic, so it's okay without length limit.

I got another case to call without coin validation logic. I've just made commit to fix it.
