[Feat] Different speeds for different types of blocks

[VoidLeech]

Goal

Add additional tags for different kinds of speeds, allowing distinctions between different kinds of paths:
Long distance paths might consist of the typical path blocks
Shorter distance paths might be a more mixed sample of stones

Considerations

This should not affect too many areas outside of actual paths. The above can be trivially added, consider adding some additional way to mark paths instead, so users can mark their paths but use whatever block.

Added this part in bd99d2f /w default path speed
Laggy-trails and quickest-roads should probably use the same techniques, but performance-wise should probably be distributed as separate packs.
