Draft: Various improvements for the chemistry module
- new routine find_isomers
- new routine fine_reactions
- make use of super().load_reactions to have consistent network summary
- improvement for writing KIDA networks. Now it is possible to add reactions to the network. But still experimental.
- parse_stoichiometry deals with more special cases
TODO
- clean code
- maybe move some more routine from the ProDiMo stuff in ChemicalNetwork to prodimopy
- finish improving the species mapping tool, or maybe extract it completely from prodimop.
