v0.2.0

• New features
  • Requests are serialized to each ATECC508A/608A through a dedicated
    GenServer. Two or more users of the library will no longer collide with each
    other on the same chip.
  • Command completion polling. This shortens the wait time for commands with
    long worst case completion times.
  • Response caching. A trivial response cache was implemented that removes the
    need to query the device for duplicate read requests. It's invalidate on any
    write or unknown command. It works well for the intended use cases of
    read-only use of the device normally and mostly write-only use when
    provisioning.
  • Added ATECC508A.Transport.detected?/1 to poll whether an ATECC508A is
    present.
