[tphakala]

BirdNET model is often incorrectly detecting dog barks as owls, this commit implements a filter which tracks dog barks and filters out user configured species detections if it happens within 5 minutes of last dog bark detection.

Species which are filtered by dog bark filter are configured in dog_bark_filter.cvs in BirdNET-Go config directory, file content should be species name per line, species can be common name or scientific name like:

ural owl
strix uralensis

Filter must be enabled in config file by setting

enabled: true
