Advanced Location Management

[randogoth]

Two watch faces Place and Places.

The first one is an editor for the watch location that supports several different coordinate notations:

• Latitude & Longitude in both decimal format and Degrees, Minutes, Seconds.
• Open Location Code (aka. PlusCode) and Geohash fixed to 10 digits.

The second one is an optional addition to the first and allows to save up to 5 different locations with a custom name and quickly swap between them.

-------> More details in the header files. (place_face.h, places_face.h)

This also attempts to establish a file <place.loc> as a standard for having the location optionally stored in a higher precision than the two decimal digits of the location saved in the watche's register.

File format is basically a dump of the following struct with two integer representations of a five digit decimal coordinate (DD.DDDDD * 100000)

typedef struct {
    int32_t latitude : 25;  // max value  90,000,00 = 24 bits + 1 for sign
    int32_t longitude : 26; // max value 180,000,00 = 25 bits + 1 for sign
} coordinate_t;
