### Feature Request / Improvement
I think I have somewhat of an idea on how to do this, so far have added the
following to `parser.py`:
```py
CAST = CaselessKeyword("cast")
cast_expression = (CAST + "(" + column + "as" + identifier +
Suppress(")")).set_results_name("cast")
# would need something special for the set_parse_action
```
I am wondering a couple of things:
Do we need a new class `CastableReference` or something? Worth expanding on
the `Reference` class? And once that is done, how would we propagate the new
type (Im assuming we need some way to go from a string to an `IcebergType` of
the string the user has put into the cast operation) into the scan?
This was spawned from https://github.com/apache/iceberg-python/issues/170
Happy to work on this, just would be awesome to get some context
