Make specs, rates and fluxes arrays dictionary (or dataframe)

[pb866]

Make specs, rates and fluxes arrays a dictionary (or dataframe with symbols of species/reactions as column names) to avoid having to make the search for species/reactions more convenient without find.

Dictionaries seem better solution as the are not bound to the same column length and having to have a workaround wrapping it in an outer array and are fastest.

• Test performance finding every entry for a 10.000 integer array:
  • Dictionary (fastest): 0.0023
  • DataFrame: 0.0118
  • Find: 0.4907
  • Findin (slowest): 1.2959
• Transform specs, rates, and flux arrays into dictionaries
• Revise search in DSMACCanalysis
• Make MCM version obsolete (not needed as no translation back from GECKO-A to MCM in newly structured scripts), adjust input files and read routines
• Adjust plotting to new data format
