Battybirdnet pi : WIP

[alexbelgium]

This is a proposal for a combination of BirdNET-Pi and BattyBirdNET-Pi

Logic :

• BattyBirdNET-Analyzer repository from @rdz-oss is downloaded as a sub-folder of BirdNET-Pi
• server.py contains 2 analysis logic : run_analysis (as before), and run_bats_analysis
• If BATS_ANALYSIS set to 1 :
  • Logo changes to BattyBirdNET logo
  • birdnet_recording uses the BATS_SAMPLING frequency for recording, and forces wav files
  • birdnet_analysis.py uses run_bats_analysis
    • starts the BattyBirdNET-Analyzer server
    • sends the file to it for analysis using the customized reporting.py
    • recovers the detections and continue the normal workflow
  • spectrogram_viewer adapts its frequency to BATS_SAMPLING

There is additions :

• DENOISER : only applies for bats
• timer service : allows to configure if only one model starts during a specific time, or if both run in alternance

Specific requirements : bottle (for Analyzer), and tflite runtimes 2.11.0 (not sure why)

To do :

• write readme
• check all functions
• allow both models to run at night ; which requires to duplicate files before analysis to restore the 48000 sampling rate to the BirdNET file
• Have a custom installer that would allow to only install the battybirdnet-analyzer if required to save place on small devices
