Summary0004353: Use RxJS instead of ad-hoc abstractions for event streams
DescriptionCurrently we use our own stream abstraction for things that come from the wallet's database, which can only be queried asynchronously.

Instead of using our own API for streams, we should use RxJS, which is widely used, comes with TypeScript typings and implements the helper functions we're currently implementing ourselves. These helper functions had bugs before, and are a pain to debug.

Another place where RxJS would be useful is the event handling for the UI. Currently we're doing e.g. debouncing of events in the mint selection dialog manually, using observables (which do provide a debounce function) would make that code much shorter and readable.

Right now it doesn't make sense to switch, also it's a really fat dependency. Our own, small abstractions are good for now.

Our use is too specific to databases to use RxJS.

Alternatives to our own query mini-language would be Google's lovefield [1], but it's a very large dependency and doesn't support types very well out of the box.

Resolving this for now, our UI code doesn't use any streams right now, once we really need this we can think about using a library like RxJS for it.
