check if we need to add some kind of filter for background noise?

Is your feature request related to a problem? Please describe. Currently the classifier runs over everything. in the interest of energy use, maybe we should try to have a simpler feature extractor or other kind of filter that checks if something interesting is in the data chunk and throws it away if there isn´t?

• [x] check what bridnet-analyzer does, if anything
• [ ] check if the users deem it necessary - they mentioned energy issues
• [ ] if yes: check what possibilities we have for implementation, also with the users/their expert

Hammad mentioned that birdnet-pi removes results that only contains human generated data. We could do this, too.
