by Vince LarsonPlot fractional approximate biases based on log-transformed parameter values.
Then the approximate biases should match the default simulation biases
when the number of parameters equals the number of metrics.
Moreover, linearizing the original, untransformed parameter values
isn't necessarily a better approximation. It depends on whether global
model metrics vary linearly or logarithmically with changes in parameter values.
Also make other minor changes, as follows.
Update regional netcdf files to Zhun's versions from 20210505.
Change default hovermode so that when a user hovers over a line
on a plot, the values from all lines pop up together.
For #910.
