replace the current teachable machine model with any other model built from scratch

[Asher-MS]

The current machine learning model used in the attention meter is built using Google Teachable Machine which makes it very easy to build models but it has its own demerits ( Not extensively configurable,...)
replace the current model with any other model written in any other framework or language(preferably tensorflowjs).
The model must be able to differentiate between a attentive person and a person who is not paying attention.
