Also ignore EDGE pixels when computing threshold for detection
Merge branch 'u/jbosch/DM-551'
Check for footprints that don't overlap image in forced photometry
Merge branch 'u/jbosch/DM-618'
Fix format string for exception thrown when footprint transform fails
Catch exceptions thrown by the measurement framework (in e.g. transforming footprints)
Do not use approximate exponential function.
Make IdSpanCompar more deterministic.
Replace tabs with spaces
Merge branch 'u/yasuda/DM-698'
Add option to use the fallback value at the edge of the image

Also unpack variables to allow us to implement this (but don't do so yet)
Improved comment on defectType
Merge remote-tracking branch 'mitaka/tickets/DM-670' into mitaka_master
Adapt to new mask bit NO_DATA replacing EDGE (DM-669)

NO_DATA means a warp/coadd pixel doesn't map to a CCD.
EDGE means a pixel is near the edge and couldn't be searched
for sources.
