Title: Improve backward compatibility of lexer without restricting non-greedy use cases

* Configurations which cross a non-greedy decision in the lexer are treated as ordered alternatives (leftmost match wins)
* Configurations which do NOT cross a non-greedy decision in the lexer are treated as unordered alternatives (strict longest match wins)
