DRG, DRGEP+SA is compatible with Cantera 3.0

[sandeepjella]

Edits have been made in several files that update the code to use Cantera 3 changes. Notably, the use of adaptive preconditioner from Cantera 3 speeds up the mechanism reduction.

Pending work:

• Sensitivity analysis will crash when trying to remove species important and its intelligence should be improved. A fairly simple criteria can be used based on the DRGEP ICs.
• Automated testing and MWE to be added.
• Additional examples.
• Jupyter Notebook version to expose the DICs, PICs, visualize network and allow manual intervention.

Errata: soln2cti.py is zeroed out and uses the write_yaml function from Cantera. However, the filename is not changed (still called soln2cti.py)
