Added support for Treadmill Calibration. When saving a Treadmill running activity for the first time, you will be given the option to enter the distance that the treadmill recorded. This will improve the accuracy of the distance that the watch records during future treadmill activities, and it will update the overall distance and average pace of the activity you just saved. You can also choose to calibrate when saving any treadmill activity. When you are done with your activity, stop the timer. Scroll down to 'Calibrate & Save.' Then, enter the distance that the treadmill recorded. For accuracy, these options become available when recording an activity longer than 1 mile or 1.5 kilometers.
Fixed an issue where the device was unable to process large GPX files.
Fixed an issue where large values for ascent could overlap each other on the elevation plot page.
Fixed an issue where a FaceIt CIQ watchface would flash, when transitioning to the watch face. (Requires Display 2.31)
Fixed an issue where Sunrise and Sunset times were showing invalid values on a CIQ watch face. (Requires Display 2.31)
