e339cf15e8 SCHEMES: Add symmetry preserving optimizations to isothermal KEPES Riemann solver 
- Update riemann_mhd_iso_kepes() subroutine to include missing symmetry
  preserving optimizations.
- Ensure consistency with the adiabatic version by adding and utilizing
  the ch variable.
- Correct the initialization and usage of transformation matrices (rm and tm).
- Adjust calculations to ensure symmetric properties, particularly in the handling
  of variables cs, ca, and cglm.
- Include appropriate sign functions for consistent behavior.
- Make changes to the calculation of intermediate variables to maintain symmetry
  and consistency.
- Adjusted flux calculation to correctly apply symmetry preserving
  terms.

fb25489487 SCHEMES: Fix ROE solvers for MHD. 
The tearing test problem was numerically unstable in the adiabatic case.
Setting bty to 1 in the case of br beeing zero solved the issue. Make it
consistent for the isothermal ROE solver as well. Additionaly, one typo
was fixed in the calculation of the left eigenvectors.
