Show Deno Cache Download Progress

[asbng]

⭐ Suggestion

Whenever Deno (re-)loads its caches, show a status message that lets the user know that something is going on. In a first implementation, stdout of the deno command could simply be piped to the UIX user. A more favorable solution would ultimately be the live parsing of deno's stdout to only show a one-line concise status message about which modules are currently being downloaded.

📃 Motivating Example

Especially on slower internet connections, it can sometimes take a minute or more for Deno to populate the caches. In the current implementation, the user simply sees as blank terminal screen. The only way to distinguish it from a hanging black box would be to open up a network inspector software and see if Deno is actively pulling data from the network.
Having a live status message would further reduce the perception of UIX being "slow" when it's actually doing a lot of reasonable work under the hood.
