Dependency issues in python package

[jarkenau]

When installing seerep-grpc via pip the following error occures:

Installing collected packages: flatbuffers, protobuf, grpcio, seerep-grpc
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
grpcio-tools 1.46.1 requires protobuf<4.0dev,>=3.12.0, but you have protobuf 4.21.12 which is incompatible.

Should be as simple as downgrading protobuf.
