Add support for EU tunnel codes

[otbutz]

This is a followup PR for the discussion in #1711 which adds the ability to honor restrictions on the transport of hazardous goods through tunnels.

Changes so far:

• added support for alternative tagging schemas hazmat:adr_tunnel_cat and hazmat:tunnel_cat
• check for the presence of tunnel=yes when dealing with hazmat subtags like hazmat:B to avoid collisions with tags in Finland.

You can run the following overpass turbo query to visualize the ways with supported tag combinations:

[out:json][timeout:25];
// gather results
(
  way["hazmat:tunnel_cat"];
  way["hazmat:adr_tunnel_cat"];
  way["hazmat:A"="no"]["tunnel"="yes"];
  way["hazmat:B"="no"]["tunnel"="yes"];
  way["hazmat:C"="no"]["tunnel"="yes"];
  way["hazmat:D"="no"]["tunnel"="yes"];
  way["hazmat:E"="no"]["tunnel"="yes"];
);
// print results
