Compress the trained species classifier model using tensorflow lite

[KatrionaGoldmann]

Convert pytorch models to tensorflow lite following: https://github.com/omerferhatt/torch2tflite

[KatrionaGoldmann]

tflite-runtime requires python ≥ 3.7, whereas baskerville only has 3.6.8 by default.

So to run:

• [x] Install pip packages with python 3.8
• [x] On baskerville use amber/projects/torch2tflite/bask_setup.sh

[KatrionaGoldmann]

Conversion steps:

• [x] pytorch to onnx
• [x] onnx to tensorflow
• [x] tensorflow to tflite

Evaluation:

• [ ] compare accuracy of pytorch vs tflite on test batch (addressed in https://github.com/AMI-trap/on_device_classifier/issues/13)
