Step 1: gPRC connection to LND

First step is following these instructions:

https://github.com/lightningnetwork/lnd/blob/master/docs/grpc/python.md

Which immideately fails because

╰─± poetry add grpcio grpcio-tools googleapis-common-protos mypy-protobuf

Fails with a version conflict.

poetry add grpcio grpcio-tools@1.62.0 googleapis-common-protos@1.62.0 mypy-protobuf

Works.

channel = grpc.secure_channel("10.0.0.5:10009", creds, options=(('grpc.ssl_target_name_override', 'umbrel.local',),))
