core: add CRTP base class to unit types

Browse source 
The goal here is to add general addition and scalar multiplication
functions to the unit types.

Thereto, we need a CRTP
(https://en.wikipedia.org/wiki/Curiously_recurring_template_pattern)
base class.

However, this breaks compound initialization, so we have to use
named initializers:
	weight_t { 2000 } -> weight_t { .grams = 2000 }
The good thing is that this is exactly how these classes were
supposed to be used: make the unit explicit!
