Add interactive DCP atoms table to docs

[langestefan]

This is purely a docs PR.

Adds an interactive atoms table using a vue component.

The atom tables are now json files, which could be automatically generated from the code as well.

The entries look like this:

  {
    "atom": "geomean",
    "meaning": "\\left(\\prod_{i=1}^n x_i\\right)^{1/n}",
    "domain": "\\mathbb{R}_{++}^n",
    "sign": "Positive",
    "curvature": "Concave",
    "monotonicity": "Increasing"
  },

This is then imported into the markdown file as raw HTML and rendered directly.

@raw html
<AtomTable src="dcp" />
