jan-scraper v0.0.2b2

Added the possibility to activate more than one model at once within activate_jan_api function: this may be incompatible with RAM/CPU resources and/or may result in the activation of only one model, which may also happen not to be the desired one: set the parameter auto to False and activate the API manually to avoid this inconvenient.
Check out the README and the user_case_API.py for more detailed explanations.
