Add ability to upload in-security demos and COGS

[megdeb]

This feature may be a future enhancement to Co-Pilot, but having the ability to load these on the device to use during training may also be useful, as long as there is a smooth transition between the different components.

(in)security demos show participants specific vulnerabilities and risks associated with different behaviors, while then providing information to participants on how to mitigate them. These demos focus on a more hands-on learning experience, rather than a lecture style training session. https://github.com/schloss/insecurity-demos

Another component that would be useful to incorporate into Co-Pilot are COGS (Challenges, Observations, Games and Simulations). COGS focus on actively engaging with participants through different drills and games, while allowing them to practice the new set of skills they have acquired.
