[1.15.2] Road Stuff 3.0.0 • 1.15.2 update

This build brings Road Stuff to Minecraft 1.15.2!

Starting from 3.0.0 Road Stuff requires now Mapper Base to be installed!

Changelog

• Updated to Forge 31.1.19 for Minecraft 1.15.2
• Added Mapper Base dependency: this library will now provide basics to Road Stuff for code but also contents like basic asphalt and concrete blocks, or bitumen generation.
• Added all color variants for reflectors, luminescent reflectors and guardrails.
• Some code refactoring done everywhere.

As usual, remember to report any problem or bug you may encounter.
