Create syntax highlighting/linting profile for fmdtools modelling

[hulsed]

Need to highlight such that:

• states/components/attributes are shown as property of the function/component/etc
• connected flows/attributes should also be inferred from model file, otherwise left grey?
• non-existent/misspelled flow attributes should be highlighted
• self.x where x is not in either should be highlighted
• Should be able to be imported into VS Code and Spyder (pyflakes/pylint?)
