bug: Describe fails when schema has FixedBinarySize columns

[jay-dee7]

Describe the bug

When using describe method on dataframe, the operation fails with the following error:

Arrow error: Cast error: Casting from FixedSizeBinary(16) to Utf8 not supported

This looks like a straightforward bug fix since explain works just fine and this is probably just a missing case.

I would love to send a PR over if this is indeed a bug :)

It seems like this is a limitation of the underlying arrow library rather than an issue with DataFusion itself.
