allow for deleting and overwriting of fire results

Include the ability to delete fires as well as overwrite them. The Parquet file doesn't allow for editing or deleting inherently. It would just need to be regenerated after files are deleted from object storage

Start by tracing how fire results are written to Parquet and object storage; the issue does not name specific files or tests. Define the delete and overwrite flows, including when the Parquet file is regenerated after stored files change, and verify that removed or replaced fire results are no longer represented.

Written by the indexing model from the issue text.
