core: introduce a few user-defined literals for unit types

Browse source 
Thise makes initialization of unit types more palatable.

For example:

    surface.time = sample.time - duration_t { .seconds = 20 };
=>  surface.time = sample.time - 20_sec;

    delta_depth.mm = feet_to_mm(1.0); // 1ft
=>  delta_depth = 1_ft;

    get_cylinderid_at_time(..., { .seconds = 20 * 60 + 1 }));
=>  get_cylinderid_at_time(..., 20_min + 1_sec));
