Track - Should it be an enum?

[theangryangel]

Following on from #111, does Track also make sense to be an enum?

If yes, where do we draw the line?

• Is it location (i.e. BL)? Probably not
• Is it location + combo (i.e. BL1, BLX)? Maybe?
• Is it location + combo + direction? Maybe?
• Is it actually a composite? i.e. BL, with combo = 1, reverse = 0?
• Something else?

This one is a little bit fiddly. 🤔
