Create exhibitive python app

[zawadzki-dawid]

We have created python application which we are going to use in order to present capabilities of our voice assistant platform. We decided to not add more functionalities to board itself, instead we send instructions over UART port to PC where python script is working. So far our python script can:

• read user unread gmail mails,
• return information about wheather,
• control music player.

Code can be found in voice-assistant repository.
