Update API to modern Dart implementation

**Is your feature request related to a problem? Please describe.**
Bringing the modern v8.x Bloc Dart implementation to Bloc.js, specifically the `bloc` package. A separate issue and pull request can be made for `react-bloc` updates.

**Describe the solution you'd like**
Most of the desired API already exists as a WIP in a separate repository that I've created. I'd like to incrementally merge those API changes, as well as build related changes that may need to happen in the least invasive way possible. Certain dev dependencies may need to be updated such as linting, bundling, and transpiling dependencies, ex: `tslint` has been deprecated since 2019, which can be replaced with eslint.

**Describe alternatives you've considered**
none
