The project that adds support for updates/deletes for time-series collections supports modifications to already compressed buckets but leaves modified buckets in the uncompressed state.

For deletes:

1. Partial bucket deletion results in an update to the bucket document (preserving the _id value)
2. Full bucket deletion results in a deletion of the bucket document

For updates, same as deletes for the original bucket document, and the updated measurements will be inserts of new bucket document(s)

We need to re-compress the original bucket document for the partial changes made to it.
