Description
When Meredith Rawls ran DcrAssembleCoaddTask it failed on patches with large regions of no data. The Task should test whether subregions contain data at an earlier stage, and skip them or fail earlier. See the log below for an example:

This resolved the problem (when I used the DM-16632 branch, which includes this fix). Thanks!
Please review this by re-running the failed Decam patches.
