API Package should be generated in a separate repository

[akaszynski]

#91 will fail until we can update the protobuf files. Autogenerated files should not live in this repository, but rather should be generated from protobuf files in the ansys org.

Sample offending file:
https://github.com/pyansys/pyDyna/blob/main/src/ansys/dyna/core/solver/dynasolver_pb2_grpc.py

See protobuf compilation helper for how to get started with this migration.

Partially solved by adding the server in https://github.com/ansys/ansys-api-dyna.

Tracking this in #189
