Changes:
- Add CalibrateAccelerometer method to auto-calibrate already collected at-home data
- Add rolling statistics methods in utility submodule
- Fix gait metric computation when using autocovariance functions (Gait Symmetry Index, Stride regularity, etc)
- Use median for summaries of previously computed metrics (GSI, regularity, etc)
- Add orientation correction (Moe-Nilsson 1998) as optional to Gait processing
- ReadBin now returns a temperature array that is the same length as the time and acceleration arrays
- Standardize file reader function/class names
- Rolling mean and standard deviation now use almost no additional memory during computation
- Fixed a bug in the rolling moment extensions that was causing segfaults (return dims freed before final use)
