(3) edit now; before rotating

quick_adcp.py --yearbase 2003 --use_smoothr --datatype oslta \
--steps2rerun apply_edit:navsteps:calib --auto


(4) rotate, check calib


see cal/rotate/fix_gyro.m; includes
- converting ENS file headings to gyro/*hdg.rbin
- converting N2R files to ashtech/*.adu.rbin
- fixing vmdas timestamps (bad utc conversions)
- runing mk_gyrodh.m

now rotate using "rotate rotate1.tmp" (gyrodh.ang)
and check calibration:

quick_adcp.py --yearbase 2003 --use_smoothr --datatype oslta --steps2rerun navsteps:calib  --auto
