Migrate models from experiments to the model ZOO

[tersekmatija]

Start with the why:

There are many converted models that are available to the community. Currently, most of them are located in the luxonis/depthai-experiments repository. By moving them to the model zoo, we are collecting all the available models and additional information in one location. This will allow an easy search over the models with the help of the new web based search engine, as well as reduce the size of the luxonis/depthai-experiments repository.

Move to the what:

Moving the models from the experiments to the model zoo. Due to experiments usually containing .blob files, generation of .xml and .bin files would be required in most cases. Afterwards, experiments could be updated to use the model zoo.

Move to the how:

1. Prepare a list of models in luxonis/depthai-experiments that are not yet in the model zoo + model from other repositories.
2. Upload them to the model zoo.
3. Update experiments in luxonis/depthai-experiments to use the model zoo.
