This adds true change observability to the store,
as the `.subscribe()` callback triggers with every dispatch,
even if the data didn't change.
Now `store.observe(onChange)` can be used to only be notified
once the state data actually changes

* feat(GUI): add convenience localstorage class
We add a class `Storage` and accompanying helper methods that makes
localStorage usage easier.
Change-Type: patch
Changelog-Entry: Add a convenience Storage class on top of localStorage.
This adds the capability to configure settings via a `.etcher.json` file,
either in the user's home directory, or the current working directory.
In the case of the home directory, the config file is `$HOME/.config/etcher/config.json`,
while on Windows `$HOME/.etcher.json` is used.
The defined settings are merged with localStorage settings, and preceding
configuration files.
If both are present, the current working directory takes precedence.
Change-Type: minor
Changelog-Entry: Add support for configuration files
