Options for controlling the matching based on relationships between edges

[maxitg]

#344 will help here.

The problem

The "MultiwaySpacelike" evolution already exists, but we also need to allow other types of evolution. The only two I can think of that would make sense globally are "SpacelikeBranchlike" and "SpacelikeTimelike".

Additional context

Requires implementing a new option on the WL side, but most of the implementation is in C++:

• Implement "MultiwaySpacelike" evolution;
• Implement "SpacelikeBranchlike" evolution;
• Implement "SpacelikeTimelike" evolution.
