Additional notes for reviewers

I know this is still a draft, but do you think we should completely remove the support for parler or should we keep it as an optional, additional dependency for people that might want to experiment with another model and dont mind downloading a huge package? To clarify, I agree parler shouldnt be in the main dependencies of the project, but have it as an option.

We can keep both set of functions supported in the API but chose to use a specific one in the demo.
I did the changes here the fastest way, which was to completely overwrite it so we could test the draft in the demo.

After our discussions, I am closing this.
It is probably smarter to use one of the frameworks @Kostis-S-Z researched instead of having more than 1 model-specific functions
