map_loading could not get correct resource for AprilTags

[jasonhu5]

The below function fails to look up the resources for apriltags.

duckietown-world/src/duckietown_world/world_duckietown/map_loading.py

Line 327 in 4e72509

def get_texture_file(tex_name: str) -> str:

Because tags_db.py tries to find the resource with this name:

duckietown-world/src/duckietown_world/world_duckietown/tags_db.py

Line 23 in 4e72509

texture = f"tag{f}_{tag_id:05d}.png"

while the get_texture_file function on the top always tries to append .jpg or .png for the lookup.

Following is a way to fix it:

if (tex_name in resources):
    return resources[tex_name]
