Canonical form: Jumbled order of nth weekdays

[westnordost]

This parser outputs a canonical form of the parsed opening hours string for better readability. However, there seems to be a bug for nth weekdays.

E.g. "all Sundays except the 2nd Sunday of each month": Su[1,3,4,5] is changed to Su[1,5,4,3].

This does not increase readability, actually, why change the order at all?

Without actually checking, I'm fairly sure that is an artifact of how the numbers are collected during parsing and it is just missing a Collections.reverse at some point.
