Add VarHandle variants for `Packed64` to investigate whether using
VarHandles
improved performance or not.
This PR introduces two new Packed64 variants:
~ Packed64LongLong
Same as Packed64 however instead of using direct array access, it
relies on `VarHandle`. It's main purpose benchmarking.
~ Packed64LongByte
A different implementation of Packed64 backed by a byte[]. It reads the data
as a
long and in case of overflow reads an extra byte. The algorithm is slightly
different
since the overflowing bits need to be computed on a different block size (8
vs 64)
which requires extra cycles.
