I've run into two issues regarding commit 70d606e

1. I can no longer geocode a watermask (created iwth generate_mask.py ) as it doesn't have the heading attribute:
   -/mintpy/utils/utils0.py", line 222, in auto_lat_lon_step_size az_angle = np.deg2rad(abs(heading2azimuth_angle(float(atr['HEADING'])))) KeyError: 'HEADING'

2. The size of the geocoded files (for example temporal coherence mask) is no longer consistent with the original radar coded mask (and I think width/height are flipped). Prior to this commit, the sizes were consistent. I'm not sure if this is expected or not.
   -the original size was (1504 x 3177) and is now (3213 x 1798).

Any thoughts on fixes? I can help implement.
