Viewer - Custom "Loading" Component

[joseph-bayer]

I'd like to display a custom component instead of the "Loading" text that displays while the manifest is fetched & loaded into React.Context (code here)

1. Is this something you'd be interested in me implementing?
2. If so, what solution would be acceptable? For example, we could pass in a react component into the config and display that instead of "Loading" (but only when that config value is populated)

Hey @joseph-bayer this would be a great addition. That Loading text has always bothered me a bit. Updating this default component and setting up a way to pass in a custom React component through the configuration options seems like a great step forward.

We're open to PRs and if our configuration models make sense and you have thoughts on how this could work, please contribute forward!
