Subject: [PATCH 1/2] Increase range for single id in Tuple (from 16 to 32bits)

Now single id in Tuple can be in higher range (32 bits per id) thanks to ArrayBuffer

first we store each id in ArrayBuffer/DataView(8 bytes = js number) as uint32 at 0 byte and 4 byte
second step is to get key by getting js number (8 bytes from whole buffer)

thats it! :D
