feat: add type hints

[ansjmoody]

Description

Please provide a brief description of the changes made in this pull request.
Add type hints to all source code. Update parameter types in comments to match.
Consistent formatting for commented parameter descriptions.
Updated rst files to include more classes.
Added SherlockNoGrpcConnectionException and raise this exception when there is no GRPC connection.
Fix and reduce warnings.
Fix bug when setting enum values in Analysis.update_pcb_modeling_props().
Use type constants instead of strings in examples and unit tests.
Removed "List of" in the parameter documentation description for collections. Sometimes the type isn't a list so this wording can be confusing.
