5a515240ac OptimiserSuite: Use brackets instead of parentheses as syntax for repeating abbreviation sequences
- We want to start accepting abbreviation sequences on the command line and parentheses would always have to be escaped in that context.
- There wasn't any important reason behind choosing () rather than [] or {} and it still isn't too late to switch.

4e7c1c7876 OptimiserSuite: Add two maps for converting between step names and abbreviations
- Abbreviations match those used in yulopti.
- I considered using boost::bimap but I think it would be an overkill. Two simple maps are good enough in a situation where data is constant and there isn't much of it.
- I could also use InvertibleMap from libsolutil but I don't even need any of its methods since my map is a constant. I also don't need the inverted map to store sets because my values are unique.
- The reverseMap() is generic enough to be moved to some global file with utilities but I don't sure if it's going to actually be useful to others in practice.
