Enable weighting of TDE boundary conditions

[brendanjmeade]

Add parameters to *_mesh_parameters.json that provide scalar values for setting the weights for the TDE boundary conditions. This will enable more tuning between smoothing and boundary condition application.

@jploveless What do you think of this?

[jploveless]

I think this is very important to implement! I also think that it requires being able to manually set color limits on the plot, to make sure that various weighting factors show the expected influence on the slip distribution.

Sound good. I'll start just by adding reasonable variable names for this to the cascadia mesh file. See: 8be59bd

The only one of these parameters that is currently used is the one for the bottom BC on each mesh. That weight is currently applied to all BCs associated with that mesh. The others are read in but not used for the QP+KL case. Change? Also, for the QP+KL case the command.tri_con_weight is not currently used but it could used to pre-multiply all of the individual mesh weights as a sort global scaling

Targets:

• per mesh weighting with DWE
• per type [bot, top, side] weighting with DWE
• Overall weighting with DWE
