Enforce minimum AI inference bounding box

[hotzenklotz]

Context

Sometimes user want to try out the AI inference features. The upload a tiny datasets and launch this feature or use a really small bounding box. In some cases this BB is too small to run an AI segmentation and the WK worker will crash. We should prevent users from triggering these jobs.

Expected Behavior

WK should enforce a minimum BB in the UI and prevent users from launching a worker run destined to fail. AFAIR, we already enforce a maximum limit for AI jobs.

Current Behavior

The worker crashes with with an Assertion Error:

AssertionError: Your dataset size in the prediction mag ([ 1 89 250]) is so small that no valid prediction output shape can be found (minimum is (2, 50, 128)).

Steps to Reproduce the bug

1. Launch AI job with a really small BB
2. Kaboom
