Tensorflow lite micro on Arduino Nano 33 BLE Sense: Part 4 Training Neural Network.

After collecting data in Part 3. We will train a neural network. I will use google colab for 2 reason.

1. I broke my nvidia setup on my computer.
2. Google colab is a nice way for people to run neural network based code without the hardware.

We can potentially turn into a script, but I want the GPU speed up, and I broke my setup on my computer.
