FE: Screen Reader Accessibility

[ClarkGH]

Very Low priority.

The slideshow library can be unfriendly to screen readers, or accessible keyboard controls. This can be mitigated/resolved by only allowing one or two videos to be uploaded.

Since we're taking screenshots of videos, I question the validity of using a screenreader.

Either way, good feature to build up.

The problem lies with the pure-react-carousel lib having a few bugs.

Might be better off making our own slideshow in the future if this is a real problem.

de-prioritizing.
