Basic quadrant, strike/dip, and rake parsing.
`mplstereonet` expects measurements to follow the
"right-hand-rule" (RHR) to indicate dip direction.
If you have a set of measurements that don't necessarily follow the RHR, there
are a number of parsing and standardization functions in `mplstereonet` to
correct for this.
