Calculate the Wood-Anderson amplitude equivalent

[hadigh]

Describe the solution you'd like
the estimate of Wood-Anderson amplitude would be calculated by gmprocess for all available components (vertical and horizontal) and be stored as a waveform metric in the workspace file

@hadigh I just want to clarify: You want this as a metric, e.g., the max absolute amplitude of the Wood-Anderson response? Not the waveform doesn't need to be stored, right?

[hadigh]

@emthompson-usgs Yes, that is correct
