gz sdf command-line tool should be in sdformat

The gz sdf command line tool really should be in this repository. It's a pain to compile all of gazebo just to use gz sdf, when it doesn't use anything special from gazebo.

Once ign-tools is released, sdf can make a plugin for it.

The equivalent ign sdf tool was added to SDFormat on this PR.

was kind of surprised this tool isn't directly a part of sdformat itself. Is that because of all the file system searching necessary that's tied to gazebo/ign? Also, sorry for blowing up your github inbox. I'm just getting spun up on ign related stuff prompting a lot of questions and observations.

I believe it was just more convenient to implement the command using ign-tools than duplicating a lot of the code inside SDFormat.
