MPRK: support slow-fast and slow-medium-fast partitioning
Takes long than expected because of a bug that sets an IS with a wrong RHS name:
ierr = TSRHSSplitGetIS(ts,"fast",&mprk->is_medium);CHKERRQ

MRK: bug fix for more than 2 partitions
- The implementation has been improved significantly (much easier to understand)
- At each level, the time integration of the fast components is viewed as a r
MRK: bug fix for more than 2 partitions
- The implementation has been improved significantly (much easier to understand)
- At each level, the time integration of the fast components is viewed as a refinement to the solution at previous level
- The refinement is done recursively
