What Am I doing:
#13254
This is to add in the vectored IO path to Iceberg
How am I doing this:
Adding the needed methods to Iceberg's Parquet IO implementation.
Defaulted OFF to the default Iceberg Stream and overrode it for AAL where we support it.
Added a mapping from parquet's object range to an iceberg specific one and then added a mapping from icebergs object range to AAL's
Depends on #13347
Note this includes commits from another: PR
this commit: 85afb89 is the one for read vector.
How have I tested this
