Add support for HKQuantityTypeIdentifierDistanceDownhillSnowSports

[MasterHamster]

Right now the package does not support requesting permission for SnowSports data.

I would be really happy if you would add it :)

Can anybody please help me i need code example to request for permissions and then get date for DownhillSkiing

You could probably see how I accomplished adding permissions for workout routes in this pull request #223. You will most likely need to add the permission to the typesandpermission file.

I just added one for RunningSpeed if you want to use this PR as an example - #249
