Pull #163

Define method for merging append deltas into static metadata db file

Why these changes are being introduced:
* TDA requires a method to support regular merging of append
deltas into the static metadata.duckdb database file as new rows
and then deletes (the append deltas) once merged.

How this addresses that need:
* Add 'merge_append_deltas' method
* Add unit test

Side effects of this change:
* It's worth noting that this method, when run, will delete the append
delta parquet files that existed in the directory at the time of
execution.

Relevant ticket(s):
* https://mitlibraries.atlassian.net/browse/TIMX-528
