~cadence/tube#42: 
Properly handle non-existing channels

Currently, this deleted channel returns a stackstrace on NewLeaf https://www.youtube.com/channel/UC6v6ljwkDGjk8Q7Dj-yjuqg

Traceback (most recent call last):

This should be properly handled, and the same way as Invidious API.

The error code also needs to be handled in CloudTube.

This should be properly handled, and the same way as Invidious API.

Invidious says: Missing hash key: "interactiveTabbedHeaderRenderer" (KeyError) from /usr/share/crystal/src/hash.cr:1027:11 in '[]' from /usr/share/crystal/src/json/any.cr:102:7 in '[]' from src/invidious/channels.cr:831:14 in 'get_about_info' from src/invidious.cr:2283:15 in '->' from /usr/share/crystal/src/primitives.cr:255:3 in '->' from /usr/share/crystal/src/primitives.cr:255:3 in 'process_request'

So I think I'll just return, "This channel does not exist".

Implemented in NewLeaf in commit 57b0a88a2e4af22ed6003a9b79f4ca7711317a9e.

CloudTube will wait. I need a better abstraction system for the calls to the instance before I implement this, or else the codebase will become more messy than I deem acceptable.
