Even when removing the whole oal.util.packed package, the JAR size is still
2.1MB.

Right, I don't mean to complain about the packed package or single it out
(though I have concerns about the massive specialization),
I was pointing out the larger issue of bloat. There are definitely other
problems too.

These classes are not only used to store large int arrays in memory but also to
perform encoding/decoding of short sequences, such as in BlockPF. If we want
BlockPF to remain fast, 5 is probably too low. Mike tested BlockPF with an
unspecialized decoder and it showed a great performance loss :

But I don't think an unspecialized decoder is necessarily fair. I think we
could optimize the low bpv that we would find in freqs/positions and then have
a unspecialized fallback or whatever.
I have concerns that specializing every bpv just means that nothing is even
getting JITd and actually makes things worse.
