Integrate DeepForest tree crown and bird detector model

[holmbergius]

Is your feature request related to a problem? Please describe.
Scout could have a clear application in tree crown detection/counting and species and condition labeling (e.g., dead) as well as bird counts. Integrating the Deep Forest tree crown detector and bird detector would open up new avenues of use, and these models already exist and are compatible.

Describe the solution you'd like
I would like DeepForest's tree crown and bird detectors to be assignable models in the Scout Task creation interface.

Describe alternatives you've considered
DeepForest is the current state-of-the-art in general tree crown detection.

@LashaO Do we have any documentation around adding additional models to Scout, or is this a from-scratch effort?

@TanyaStere42 This commit would be the best demo of adding a new model: WildMeOrg/scoutbot@ebf48c7

This would work seamlessly for models trained through our most recent pipeline: https://github.com/WildMeOrg/scoutbot/tree/main/scripts/train-pipeline-v3

Other models, like Deepforest, will require more tailoring. This is not a from-scratch effort as there is intersect between our approach and Deepforest's, but not plug-and-play either.
