Bike priority determination problem for tag combination of `cycleway:left` and `cycleway:right`

[ratrun]

Describe the bug
In case that an edge contains both tags cycleway:left and cycleway:right the better priority should be assigned, but this is currently not the case

This test fails passes:

        way.clearTags();
        way.setTag("highway", "primary");
        way.setTag("cycleway:right", "lane");
        assertPriority(SLIGHT_PREFER, way);

this test currently fails:

        way.clearTags();
        way.setTag("highway", "primary");
        way.setTag("cycleway:right", "lane");
        way.setTag("cycleway:left", "no");
        assertPriority(SLIGHT_PREFER, way);

To Reproduce
See https://community.openstreetmap.org/t/neue-routing-engine-valhalla/7204/55

The route is this one: http://localhost:8989/maps/?point=50.7897%2C6.0958&point=50.7872%2C6.0932&profile=bike&layer=OpenStreetMap

Expected behavior
The primary road should not be left and the gas station detour shall be avoided in this case

The internally assigned priority for the primary segment is "BAD":

I'll try to prepare a PR for it
