[weiji14]

Initial tutorial on creating batches of chipped data (256x256) from full-size satellite scenes (10000x10000) with different coordinate reference systems! Using example Sentinel-1 GRD GeoTIFFs over Osaka and Tokyo in Japan.

TODO:

• [x] Handle multiple UTM projections by not handling them
• [x] Integrate with xbatcher, xref #22
• [x] Batch together several chips, may need to wait for https://github.com/pangeo-data/xbatcher/issues/70
