Remove defunct scatter plot code from METplotpy/plots

[bikegeek]

Replace italics below with details for this issue.

Describe the Task

the current scatter plot in the develop branch of METplotpy does not work and is not conformant with the other plots. This was written as a proof-of-concept for using plotly. A newer version of the scatter plot is in the feature_23_scatter which is written in matplotlib and supports plotting MPR data. This will eventually replace the current scatter plot.
