Description

Hi! It would be great to develop a way to extract just ascending or descending tracks when downloading data with icepyx from regions 4 and 11 (highest latitude regions). Currently every granule in these two regions contains both ascending and descending tracks, but since we know which tracks are which it should be possible to distinguish them somehow at the point of order/download. @tsutterley had suggested separating the pieces by splitting at the minimum latitude. Open to suggestions and up for collaborating with others to implement this.

Research direction
Study the ICESat 2 data granule structure for regions 4 and 11, identify the point of minimum latitude between ascending and descending tracks, and implement a filter to extract only the desired tracks during order/download.
