DB Schema UML diagram added to doc directory
remove_tiles.py script added to allow bad datasets to be safely removed from the AGDC
Safety catch removed from src/remove_tiles.py - database and files will change for anything other than --action=report
src/remove_tiles.py multi-dataset bugs fixed and large fields excluded from queries
Add timestamps to ingest logs.

To more easily see where time is spent.
Set higher default gdalwarp memory usage.

From my tests, this decreased processing time from ~4 minutes to ~1 minute on my laptop.

Requires further testing on NCI, but gdal's default settings almost certainly seem too low.
Tweak default gdalwarp memory settings after NCI tests.

500MB was overkill, and produces similar procesing times to 250MB.

Changing the warp memory size (wm) altered the output image, so it has been removed. We don't know if the difference was better or worse (yet), but don't wish to alter output without confirmation from the science team.

Compared with the original result, our output images are half the size (due to better lossless compression), and take 8.7 seconds instead of two minutes to produce.
