      Description

      As part of LUCENE-7075, I tried to move join/ modules numeric join support away from deprecated encodings.

      Basically from what i see, its encoding Numeric/SortedNumeric in a byte[] as an impl detail, it might as well use the new 8-bit encoding rather than the 7-bit one.

      There are certain bugs in what i did, but i don't like the exceptions I see:

      What is happening here? Is the exception correct or are we missing a check?
