### Describe the bug, including details regarding any error messages, version, and platform. This is a follow-up to [this discussion](https://github.com/apache/arrow/pull/14191#discussion_r1042303944). Arrow's reader is not compliant with the spec, and requires all miniblock bitwidth values of the last block even if not necessary. This forces arrow writer to write all miniblock bitwidths to be able to roundtrip which is not a big issue. However it does mean Arrow reader would not be able to read bitpacked buffer written by another parquet writer that does not write all miniblock bitwidths. ### Component(s) C++, Parquet -- This is an automated message from the Apache Git Service.
