v2.4.0: Load and save Parquet files

[stephane-caron]

This release adds the ability to load and save test sets and results from Apache Parquet files. It also refactors the command-line tool with a progress bar (estimating the time remaining until completion) as well as a "very verbose" mode for per-call details.
