v0.2.2

This is v0.2.2 of EdiHeadyTrack.

Version 0.2.2 contains the following specific enhancements and bug fixes since v.0.2.1:

• Removed issue with plotting data where axis ticks and labels appear on key frame plots.
• Added functionality for plotting with frame number on x axis. When using Plot().plot_property() method users should specify their desired x axis property with xproperty='frame' or xproperty='time'. Where xproperty='frame', a list of key_frames can also be specified, similar to key_times. Example usage: plot = eht.Plot(head_TDDFA).plot_property(xproperty='frame', yproperty='pose', key_frames=key_frames)
• Updated Euler angle sign convention and removed initial offset, such that sign convention always follows right hand rule and typical yaw, pitch, roll axis definitions: https://en.wikipedia.org/wiki/Aircraft_principal_axes
