Update to 1.06

Upstream changes:
1.06    2021-09-08
    - Fix significant bug where at least on MacOS, if we generated a CRC of a
      key that was greater than 0x80000000, it would round down the key to that
      number exactly, casuing duplicates, and incorrect segment access
    - Added new() method, returns a reference (default hash) without having to
      do the tie() directly
    - Modify t/65-seg_size.t beyond RAM max test to cover varying error messages
      on differing OSs
    - Renamed t/67-out_of_memory.t as the tests are related to exhausting SHM
      slots, not RAM
