Protobuf can go back to protobuf>=3.12.2

[hayotensor]

Make sure to delete everything but: requirements.txt, there are other updates to RoutingTable.py to allow for updating timestamps to node_ids in the routing table for applications like Petals to use... Or even just make another commit

With protobuf>=3.12.2,<5.28.0 I receive the error:

google.protobuf.runtime_version.VersionError: Detected incompatible Protobuf Gencode/Runtime versions when loading runtime.proto: gencode 5.28.1 runtime 5.27.5. Runtime version cannot be older than the linked gencode version. See Protobuf version guarantees at https://protobuf.dev/support/cross-version-runtime-guarantee.

This should happen if you --force a pip install again and try to start a server in Petals.

This was fixed here: protocolbuffers/protobuf#18096 (It looks like)

Switching back to protobuf>=3.12.2 resolves this issue on Linux and WSL for me
