Plotting RV noise nuisance parameters

[kmhambleton]

The trace plot for an mcmc run only includes one plot for RV lnf (when there should be one per component). When specifying the individual components, i.e.: _ = b.plot(solution='mcmc_gps_sol',adopt_parameters=['sigmas_lnf@rv01@primary','sigmas_lnf@rv01@secondary'], show=True),

the first trace plot has the units of degrees on the y axis. In these plots and all corner plots, the y-axis labels for rv lnf for the primary and the secondary components are the same (i.e. sigma_lnf_rv01).
