Release Notes for 4.0.0

Add:

• Native ESM support
• Tests that cover almost all codebase

Update:

• Project has been rewritten on JavaScript
• Improved documentation

Remove:

• js-yaml has been moved to peerDependencies, so you need to install it manually
• Remove schemas and another reused exports (such as parser, createSchema and so on) of js-yaml, which means that you need to use these things from js-yaml.
• write() and read() functions will always return a Promise. Callback API is not available anymore.

For this release I've decided to rewrite the project from scratch. So, this release is not backward compatible
