We could use an environment variable to let the user choose between different ways to compute MPI imbalance. E.g.:

   VFTR_MPI_IMBALANCE=MAX_DEVIATION_FROM_FASTEST

Thinking even further, we could process a formula given by this environment variable. We already include tinyexpr to do this in the scenario files, so the overhead is manageable.

Should also be flexible for the newly implemented function call time imbalances.

This should be very easy to implement once we use Vftrace configuration files.
