feature: replacing webpack with esbuild.

[dreadera]

This PR is a continuation of the previous #178.

I have updated the build process for this library using esbuild. During this process I have made other adjustments to help with the modernisation of this application.

I have broken down each commit into a section I have worked on.

Changelog

• Fast Build Pipeline with esbuild.
• Removed webpack.
• Typescript Support & Replacing jsconfig with tsconfig.
• Removed babel.
• esm Module support Added.
• Updated eslint dependencies & rules.

Benefits

• Faster builds.
• Typescript Support.
• Smaller Bundle Size.
• Modern Library exports using esm

Gonna remove myself as reviewer -- don't have anything of use to add.

Nice work though! :)
