yannickulrich 9ecd45dadd Added FUSE support (#55)
This exposes the watches' file system over FUSE. This way, we can access files on the watch without having to go through `itctl` or developing 3rd party tools.

**Features**

- [x] read/write access to the file system
- [x] read access to momentary sensor data
- [x] live access to sensor data (i.e. WatchMotion rather than Motion)
- [x] configuration of mount point
