Handle bizarre representation of some integers in Chemkin Chebyshev output.
Handle bizarre representation of some integers in Chemkin Chebyshev output.

When merging two mechanisms in Chemkin-MFC, the output apparently writes
the numbers of temperature and pressure terms as e.g. 6.0E0 and 4.0E0
instead of 6 and 4. To handle this in Python we need to first convert
the string to float, and then on to int.
