Add typescript support

What's Changed

• Adding Typescript support by @spitliner in #17

New Contributors

• @spitliner made their first contribution in #17

Full Changelog: 1.2.1...1.3.0

Release 1.2.1

Fixes

• The rollup bundling configuration was added in a previous version, but the corresponding updates to the "files" property of package.json were not made. Thus the ES module is excluded from the npm package when used by consumers. Moreover, the bundleConfigAsCjs option is not needed anymore as we import the package.json by directly reading the file from the filesystem and then parsing it.

Release 1.2.0

• Reduces the bundle size by 500kb
• Specify supported browsers
• Update all dependencies
• Migrate from rollup 2 to 3
