📚 Context/Description Behind The Change

• Convert this repository to Typescript.
• Adds Github actions to auto-release via semantic release Dropped. It is going to be done later.

🚨 Potential Risks & What To Monitor After Deployment

The following syntaxes is not going to be supported anymore:

// ❌ Fail
import { parse } from 'search-string';
// 🟢 Replace with
import SearchString from 'search-string';
// and them
SearchString.parse()

// ❌ Fail
const SearchString = require('search-string');
// 🟢 Replace with
const SearchString = require('search-string').default;

🧑‍🔬 How Has This Been Tested?

• Unit tests working without behavior change
• TS build
• Simulate NPM publishing with npm pack. Copy-pasted the generated files to another projects that uses this and asserted that it builds fine.

🚚 Release Plan
