Unnecessary Google API dependencies in requirements

[clemlesne]

Summary

The package includes several Google API dependencies that are not actually used in the codebase, causing unnecessary bloat (~15-20MB extra).

Unused dependencies

Package	In setup.py/requirements.txt	Actually imported
google-api	✅	❌
google-api-core	✅	❌
google-api-python-client	✅	❌
google-auth	✅	❌
google-auth-httplib2	✅	❌
googleapis-common-protos	✅	❌

Evidence

I searched the codebase and found only these Google-related imports:

• client.py: from google.protobuf import empty_pb2
• rootService.py: from google.protobuf import empty_pb2

Both only use google.protobuf (the core protobuf package), not any of the Google API packages listed above.

Suggested fix

Remove unused dependencies from setup.py and requirements.txt:

- google-api>=0.1.12
- google-api-core>=2.18.0
- google-api-python-client>=2.123.0
- google-auth>=2.29.0
- google-auth-httplib2>=0.2.0
- googleapis-common-protos>=1.63.0

Keep only what's actually used:

• grpcio
• protobuf
• ecdsa
• cachetools
• (and other actually-used packages)

Impact

• Faster installs
• Smaller container images
• Fewer transitive dependencies to audit for security
• Reduced chance of dependency conflicts

Happy to submit a PR if this approach is acceptable.
