feat!: async refactor

Browse source 
this mostly has the objective of splitting fetching and visualizing, to
be able to daemonize the fetching. I swapped out ureq for reqwest,
brought in clap, removed rusqlite for full fledged sea_orm, added
tokio. Created migrations in sea_orm to reflect current db schema. Moved
data structures defititions out of app, and slimmed down gui code.
Entities collections are mostly managed by background workers and made
available with watch-channels to the main thread, which can always
nonblockingly access data. This is cool but still has some sharp
corners. Now plots don't refresh live but at specific interval. I plan
to add synchronization channels later on tho.
