make swathBounds available #99

Open oarcher opened 2 years ago

oarcher commented 2 years ago

swathBounds are available in annotation (xpath '/product/swathMerging'). ( ref Sentinel-1 Product Specification from IPF 2.9x to 3.3x , p 182)

We should be able to decode it as a geodataframe.

_NoiseLut has also a '.block' property that should be compared to those swath bounds
