Daft reader for DeltaCAT catalogs in general

[raghumdani]

This feature allows reading the DeltaCAT catalog (Iceberg, internal catalog etc.) into a Daft distributed dataframe. It also provides hints regarding data layout to Daft reader so that the reads are optimized and no worse than existing compactor.

Expected Features

• Reading entire table into memory.
• Leverage Partition Pruning using DeltaCAT metadata.
• Leverage sort order policy using DeltaCAT metadata.
• Support merge on read and hence, delete deltas.
• Unblocks [Iceberg] Daft Dataframe Reader #170.
