v2.0.0

This release contains two backward incompatible changes:

• Internet Explorer 11 and Node.js 10 or lower are unsupported. You might be able to make it work by using polyfills for TextDecoder and BigInt, but it is untested and unsupported.
• Context variables are disabled by default due to their performance penalty and need to be explicitly enabled by calling .useContextVars() on the parser object.

Changelog:

• feat: remove IE11 & node.js 10 support #178 @manzt
• feat: add ESM package export #176 @manzt
• Disable context variables by default #175 @keichi
