Fix Bounding Box Checks for Tiff Export

[fm3]

Follow-up Bugfix for #5195

• Correctly parse bounding box for size assertions (assume width,height,depth instead of xmax,ymax,zmax)
• Use Long multiplication for volume to avoid int overflow
• Remove some unused util methods in BoundingBox class
• Add some typing to public methods in BoundingBox class

Steps to test:

• with jobsEnabled, go to routes

• GET http://localhost:9000/api/jobs/run/tiffExport/sample_organization/testDataset/color?bbox=50,50,50,5000,5000,5000 (should say volume too large)

• GET http://localhost:9000/api/jobs/run/tiffExport/sample_organization/testDataset/color?bbox=50,50,50,10,10,10 (check should go through, attempt contacting jobs broker. this was broken before, as 10,10,10 was assumed to be bottom-right, which was invalid)

• (I did test these locally)

• CI should run through

• Ready for review

LGTM 👍, just one minor nitpick, feel free to leave as-is.
