feat: upgrade to MobX v6

Upgrades to the library to support MobX 6. We had to wrap the task in an `action` to prevent MobX from automatically converting it to an action.

BREAKING CHANGE: The decorator will break when a MobX decorator is used on the same method. Additionally, updated the TypeScript target to es6, same as MobX 6.

 # Changelog
 
+## 3.0.0

+* **Breaking**: Stacking the `@task` decorator with MobX `@action` no longer works in MobX v6. Instead, the task itself was made an action by default. This was done to escape the MobX auto-action behavior.

+* Add MobX v6 support.
+* Upgrade all dependencies.
