CA_ContraCostaCo_2007 missing data

[mattbeckley]

The dataset, CA_ContraCostaCo_2007, is missing a lot of data when compared with what is in usgs-lidar. The attached figure shows the boundary of data from usgs-lidar AWS bucket in red, and the boundary from usgs-lidar-public AWS bucket in black outlines. I downloaded the laz files from s3://usgs-lidar/Projects/CA_ContraCostaCo_2007 to verify that there was actually data there, and that there wasn't simply an incorrect boundary. LAZ files do exist for the entire s3://usgs-lidar/Projects/CA_ContraCostaCo_2007 boundary. It could be that there are issues with these LAZ files that caused the processing workflow to throw them out, resulting in the reduced coverage seen in usgs-lidar-public for this dataset, but I just wanted to document the issue just in case.
