encrypted." means we could basically recognize it as a Garmin GPI file,
but it's mangled beyond what we're likely to successfully read.

+ If a waypoint name is annotated with a trailing '@'NNN where NNN is
+ a number, that number will be used as the speed for POI alerts, just
+ as with Garmin's POI Loader program. The units default to metric kilometers
+ per hour, but this cn be changed to statute via the units argument.
+ A speed associated with a specific POI will get precdence over any
+ 'speed' argument provided. For example, a waypoint named "Point@30" will
+ associate a speed of 30 km/h with that specific point even if 'speed=40m'
+ is present in the output arguments.

The layout of GPI files isn't documented and our module was created
via reverse engineering. If you get a problem on reading or writing
power = Cycling power (in Watts)
prox = Proximity (in meters). Add "ft" or "feet" for feet.
sat = Number of sats used for fix
- speed = Speed
+ speed = Speed, in meters per second.
symb = Symbol (icon) name
tempf = Temperature (degrees Fahrenheit)
temp = Temperature (degrees Celsius)
