Add pyramid and wedge support

[JustinPrivitera]

Resolves #132

Adds support in the mesh blueprint for pyramids and wedges. Adds versions of braid that are comprised of pyramids and wedges.

Once merged I'll put up a PR in VisIt for the bp plugin.

The following still need to be done:

• [ ] Add to docs - crop pictures for basic wedges and pyramids + add code includes for docs
• [x] fix failing CI
• [x] add wedges and pyramids to everywhere that the other shape types are used that I haven't already

Suggestion I don't want to forget: Please add a Changelog entry.

Angle of the pictures looks good!

I would crop them down a bit so they fill more space on the docs page.

(compare pyramids with the hexs visual)

We also need the yaml output of the bluperint tree for wedges and pyramids.

And there is a small typo with the wedges entry ref in the table:

Hi. I left this in draft b/c I knew I still needed to fix up these last few things w/ the docs. Nice catch on the wedges entry ref in the table. I'll get to these very very soon 😄

I was hoping to get these last few things done before you reviewed, my bad.

@JustinPrivitera yes, no worries, I had some time to review this morning so I wanted to see how things were going :-)

Thanks, @JustinPrivitera !

Looks good, thanks for working though all of this.

I'll merge once I figure out the strangeness with silo... the silo version of wedges looks very different from the blueprint version.
