Current apache arrow implementation does not support those formats.
See https://issues.apache.org/jira/browse/ARROW-9404 for more details.

We need to write a proposal to arrow email first.

I've written a proposal to the arrow mailing list [1] [2]. However it reveals, that guys from arrow already working on supporting Decimal256, so this feature will change how decimals are defined in arrow, so we need to wait until this will be merged. Although I've created draft PR at arrow, to prepare some base for low bitness decimals.
