Change background color

[FeAx7]

3 features that I wish you could implement so that I could stop forking your project:

• For people like me using Jupyterlab in Dark mode the background color of the pics should be changed ideally automatically: -> 2 lines below to modify

div.ipyplot-content-div-%(0)s { (...) background: rgb(17, 17, 17); (...)}
#ipyplot-html-viewer-toggle-%(1)s:checked + #ipyplot-html-viewer-label-%(1)s:after {(...) background: rgb(17, 17, 17); (...)}

• Option to not show the "Show HTML" link -> I just delete this line
  <label id="ipyplot-html-viewer-label-%(1)s" for="ipyplot-html-viewer-toggle-%(1)s">show html</label>

• Option not to show Numbers on top of each pic -> I just delete this line
  <h4 style="font-size: 12px; word-wrap: break-word;">%(2)s</h4>
