Hang due to infinite loop when reading some parquet files with RLE encoding and bit packing

[anliakho2]

Describe the bug
Some parquet writers produce RLE encoded dictionaries with bit packing even if value count is not divisible by 8.
This violates the assumption decoder makes about the number of values present in the bit-packed run, causing infinite loop and hang.

To Reproduce
Attempt to read parquet file where number of values is not power of 2 but RLE encoding with bit packing was used.

Expected behavior
File should be read correctly.
