Provider Request: add support for freecampsites.net

[pirate]

This is such a cool project!

It would be awesome if we could add support for FreeCampsites.net too:

https://freecampsites.net/

Thank you! Unfortunately freecampsites.net probably isn't a fit for camply as it doesn't manage any inventory / reservations. Camply's goal is to snag hard to find reservations at sold out campgrounds so it needs providers that manage inventory for a given date.
