fix: heading speed w3c spec (#270)
* CB-11462: (all) Make sure Coordinates#speed follows the w3c specification.
Speed can have a negative value on iOS devices when the OS is not able to
determine the current speed.
This is against the w3c specification. Which only allows null and a number
value >= 0.

* CB-11462: (all) Make sure Coordinates#heading follows the w3c specification.
Heading (course) can have a negative value on iOS devices when the OS is not
able to determine the current heading.
This is against the w3c specification. Which only allows null and a number
value >= 0 and <= 360.
