Orbitdb_py

This module was originally a bridge to the nodejs version of libp2p/nodejs, but because the decision has been made to use native python libp2p instead, I am going to modify the nodejs library to export the orbitdb to an ipld CAR file, and send that ipld CAR file via libp2p to the python clients when it is requested of them. The nodejs version of the library holds all of the network metadata, model metadata, and client metadata, and it sends that metadata to the other nodes on the libp2p network upon request, and alot of this data is merged and stored so that edges of the network do not have to ask every single node for their metadata.
