Enforce payload size limit on sent message

[gdnathan]

Following up discussion on #112 .

"To actually enforce the limit, we could do something like this maybe:
src/network/wire/lib.zig

const MAX_PAYLOAD_SIZE: u32 = 32 * 1024 * 1024

const payload_len: u32 = @intCast(payload.len);
if (payload_len > MAX_PAYLOAD_SIZE) {
    return someerror
}

"

@gdnathan I was reading through src/network/wire/lib.zig sendMessage function and I saw
const MAX_SIZE: usize = 0x02000000;
which is
const MAX_PAYLOAD_SIZE: u32 = 32 * 1024 * 1024
and in sendMessage I saw

if (total_message_size > MAX_SIZE) {
        return Error.MessageTooLarge;
} 

is it not the same as limiting size on the sent message?

yes it is. It looks like it is missing from receiveMessage tho. You can add it there too
