package:// syntax in URDF

[stephane-caron]

According to the URDF "spec", mesh filenames like:

        <mesh filename="package://meshes/torso_link3.obj"/>

Should use a fully-qualified package://NAME_OF_PACKAGE/path (see e.g. this tutorial). Here that would be:

        <mesh filename="package://draco3_description/meshes/torso_link3.obj"/>

It's not a biggie since most URDF loaders add hacks around having/not having package://, but sometimes the hacks don't cover all cases 😅

In this instance, python show_in_yourdfpy.py draco3 fails in robot_descriptions because of an edge case clemense/yourdfpy#43 (but this edge case is not triggered if the package:// URI is fully formed).

Thank you for the feedback. I pushed the changes based on your comment.

And python show_in_yourdfpy.py draco3 now works 👍 Thanks!
