Perch v2 output when using through birdnet limits the min_conf to 0 #913

Describe the bug
The output of perch scores is bounded similarly to birdnet scores, but perch is in a different scale.

To Reproduce
Run Perch in CLI with min_conf argument of -10; the minimum value on the results is 0.000.

Expected behavior
Documentation should explain this, and ideally the min_score argument should accept negative values for perch. Alternatively, apply transformation to perch logit scores to match birdnet scale (0 to 1).

Desktop (please complete the following information):

  • OS: Win11 Pro
  • Version: Unclear version of what, but if it is of birdnet is 2.4.0
