Feature/new tables

[drreynolds]

Steven and I added some additional embedded explicit Runge--Kutta methods to ARKODE.

The single precision builds are currently failing with the errors below. I assume the actual table values are within the single precision range and just the rational expressions have constants that are not. Should we note this in the documentation? I'll update some of the CI testing flags shortly.

I don't see why I can't comment in-line to this item, so I'm answering in a separate comment.

Yes, I think that the issue is that the coefficients are provided in rational form, with components that have a large number of digits. I will convert these to 40-digit decimals to inhibit these warnings (I think I can easily do this with the Matlab analysis script infrastructure that I built).
