feat(rust,python): cast each parquet file to delta schema (#2615)

# Description

By casting the read record batch to the delta schema datafusion can read
tables where the underlying parquet files can be cast to the desired
schema. Fixes:

- Errors querying data where some of the parquet files may not have
columns that were added later because of schema migration. This includes
nested columns for structs that are in Maps, Lists, or children of other
structs
- maps and lists written with different different element names
- timestamps of different units.
- Any other cast supported by arrow-cast.

This can be done now since data-fusion exposes a SchemaAdapter which can
be overwritten.

We should note that this makes all times being read by delta-rs as
having microsecond precision to match the Delta protocol.

# Related Issue(s)
- This makes solving #2478 and #2341 just a matter of adding code to
delta-rs cast.
