Consider smoothness in bicycle profile

[osmuser63783]

The bicycle routing profile should consider smoothness. At the moment, the profile seems to completely ignore smoothness, because even ways with smoothness=impassable are routed over.

Exactly which smoothness values should get penalties and which ones should be avoided completely depends on what kind of bike the profile is aimed at (road bikes, general purpose / hybrid / city bikes, mountain bikes).

Examples of ways with smoothness=impassable:

• Way 4905783, and route
• Way 829106990, and route
• Way 1087976687, and route

Here is an Overpass query to find more.
