No breaking changes for end users but since it's big change - version has been bumped to 2.0.0

Fix: peer dependency blocked React v17

Fixes #27

Generating both ESM and CJS modules

react-scroll-into-view now includes both ESM (ES Modules) and CJS (CommonJS) modules

Dependencies upgrade & ESM module by default

In this release:

• output module is ESM instead of CJS
• dependencies upgrade (fix security vulnerabilities)
• bump Rollup major version (v2)
• used Rollup v2 plugins instead of deprecated once
• added react and react-dom as peer dependencies

TypeScript typings

Added new scrollOptions property to TypeScript typings

Added scroll options

Added new property scrollOptions that accepts the same properties as scrollIntoViewOptions passed to element.scrollIntoView()

That was requested in #21

Dependencies upgrade

Updated dependencies as it was required for CI Travis to properly test code.

No changes to API

Fixed ignored `onClick` prop

Resolves #15

onClick prop was added back in #11 but later on one commit removed it. Sorry to everyone affected.
