NuSTARDAS v2.1.6:

This update to NuSTARDAS provides two updates:

 - numetrology

   Updated to accommodate changes to the duty cycle of the NuSTAR metrology lasers
   used for determining the quaternions from the detector coordinates onto the sky.
   No change is performance is expected. This change allows the additional
   METSTATE values of 14, 22, 30 which correspond to different cadence modes for the
   two metrology lasers.

 - numkarf

   Updated to support HTTPS access to CALDB files in S3 buckets. 

All of these changes should be transparent to the user and are not expected to affect
science analysis.
