AI Summary: Enhance the `sotodlib` library's context manager (`ctx.get_obs` and `ctx.get_meta`) to perform more robust type checking on input observation IDs. This involves validating the format of the input ID before attempting to retrieve metadata or observation data, improving error handling and providing more informative error messages when invalid IDs are used.

AI Summary: Fix invalid escape sequences in the `sotodlib` library. Specifically, address the `\d` and `\s` escape sequences found in `load_smurf.py` and `hwp.py` that are triggering `SyntaxWarning` errors. This likely involves replacing these with the correct escape sequences or using raw strings.
