Removes the TPC-H flags deprecated in #173.

Output format selection moved from --format to dedicated subcommands:

  • --format=parquettpchgen-cli parquet
  • --format=csvtpchgen-cli csv
  • --format=tbltpchgen-cli tbl (or omit the subcommand)

Parquet-specific options moved from top-level flags to the parquet subcommand:

  • --parquet-compression=ZSTD(1)tpchgen-cli parquet --compression=ZSTD(1)
  • --parquet-row-group-bytes=1000000tpchgen-cli parquet --row-group-bytes=1000000

Tested with cargo test -p tpcgen-cli --all-features and Clippy.

doing some cleanup work, we released v3.0.0 with these commands showing deprecation warning. We can fully remove these for the next v4 release
