Increase the QGeoCoordinate debug operator precision
The current precision of 6 digits only ever guarantees
110m on Earth. That's not sufficient for some use cases.
A precision of 11 guarantees at least 8 digits after the comma since
there are at most three digits before the comma. The 8th digit
reflects a geographical precision of 1.1 mm on earth. More precision
for navigation purposes is not needed.
