Use MQTT to send bird detections to InfluxDB

[yjeanrenaud]

a small nerdy thing I just completed: https://github.com/yjeanrenaud/BirdNET-Pi-influxdb/
it gets the notifications via apprise's MQTT from BirdNET-Pi, reformats them to json, and sends them to my local InfluxDB server. Can easily be adapted for other db storage, e.g. MariaDB or MySQL by configuring telegraf correspondingly
