Speed up the tests by updating most of the sky maps to be multiordered

The following discussion from !179 (merged) should be addressed:

• @brandon.piotrzkowski started a discussion: (+1 comment)

  I've generally gotten these tests to work, with the exception of a few remaining issues:

  • The ordering of additional external pipelines is random, and changes with each run of the code. Need to have these sorted.
  • There is an extra space in one of the RAVEN circulars
  • The tests take too long to run, likely because of the heavy flattened sky maps. We should convert these to multiordered when possible to speed these up.

Also, we should only expect multiordered GW sky maps and combined sky maps at this point, so slowing down the tests just to ensure flattened sky maps works is not worth it.
