Node playlists (#239)

* Update networks.ts

Added fallback nodes and modified initNetwork for better functionality and enhanced test flows

* Update networks.ts

Should ensure that the defaultPlaylist function is correctly returning a NetworkPlaylist object with the default network settings.

* Update networks.ts

Added fallback nodes and modified initNetwork for better functionality and enhanced test flows
And modified the code to follow better practices for the defaultPlaylist and updateNetwork functions, to hopefully run better and not be caught by the linters

* Update networks.ts

Fallbacks for the playlist with network functionality deferred to rust

* Update networks.ts

Replaced get with fetch and bypassed the http calls by retuning the embedded node list directly as it matches the expected behavior in rust
