Added in sources a position field which works just like the one in panels.
Added in sources an "enabled" flag which now governs wether or not data is fetched.
Added a button to delete panels.
Tweaked UI a little
improved a lot logging, using tracing from tokio.
Now there's a subscriber which tracks log messages and makes them
available inside the state, so that we can show them in the gui.
Made a jank logs side panel.
Made panels reorderable in a kinda weird but meh way
now sources are all edited in one side panel, which opens in edit mode.
Easily move sources across panels.
Implementation has a lot of room for improvement (too many loops) but it
works for now
Committing current state, which is a simple full
screen plot with some basic features. It compiles
for both native and web. There's a basic generic
datasource impl. It currently plots random data for demo.
