Text display of slip rates and uncertainties at segment midpoints

[brendanjmeade]

Each of the line segments represents a section of a fault. Each of these has a model estimated slip rate that is stored in the segment data frame. We'd like to display these values on the main plot. There are options that we've considered for this

1. Show all values on the screen at once at each segment midpoint. This is nice in the sense that it conveys a lot of information but it could be too overwhelming to look at with hundreds of numbers on the screen at once.

2. Create a "hover" property for each segment. When hovering over a line segment display a small popup/tooltip/hover that shows the estimated fault slip rates for the current segment. This would be very cool and complementary to the color fault slip rate plotting that is already built into result_manager. See example at: https://stackoverflow.com/questions/67904185/how-to-show-values-on-hover-for-multiple-line-graphs-bokeh

The first is probably easier to implement but the second is more useful in the short and long term.

I address this in topographic_map #24. Once this is merged (it can be done automatically after review), I can close this issue as well
