Module delta_writer

Delta writers handle row-level changes by combining data file and delete file writers. The delta writer has three sub-writers:

• A data file writer for new and updated rows.
• A position delete file writer for deletions of existing rows (that have been written within this writer)
• An equality delete file writer for deletions of rows based on equality conditions (for rows that may exist in other data files).
