`hits_and_kdst_from_files()` fails silently

The function hits_and_kdst_from_files() found here is designed to continue if the required tables aren't found in the file it's extracting from when using load_dst().

This stems from the general treatment of the NoSuchNodeError, which is treated differently across all of IC on a case-by-case basis, but is regularly ignored as can be seen throughout components.py for multiple functions.

I don't believe this should be the case, but I'm glad to be told otherwise. It at the very least should warn the user that the node they were trying to access doesn't exist. This is seen in load_dst when ignore_errors = True (here), but this is by default False.

Start with hits_and_kdst_from_files() in invisible_cities/cities/components.py and load_dst() in invisible_cities/io/dst_io.py, then compare the project’s existing NoSuchNodeError handling in components.py. The behavior should no longer fail silently when required tables are missing; determine and verify the appropriate warning or error handling across the affected cases.
