Add index of lists from tokenlists.org

It'd be really nice to be able to have an index of installable lists from the index provided at https://tokenlists.org/.

This would also support installing via alias from that index, as well as the normal URI method

Specification

$ tokenlists list --all
Installed lists:
...

Available lists:
...

Dependencies

n/a

[fubuloubu]

or maybe tokenlists install --list-all
