v0.9.2

Improvements:

• Introduce ParserOptions.ExperimentalESFeatures to allow fine-tuning which experimental feature to enable.
• Re-add BindingPattern to the AST under the name DestructuringPattern.
• Prevent Literal.Value from re-boxing the return value on every call by caching it when necessary (i.e. in the case of NumericLiteral, BigIntLiteral).
• Allow accessing Node.Range and Node.Location as readonly references (see Node.RangeRef and Node.LocationRef, respectively).
• Provide an error code in ParseError (as it's not reliable to check error messages because those are localizable).

Breaking changes:

• Remove EcmaVersion.Experimental.
• Rename IVarScope to IHoistingScope.
• Rename IDestructuringPattern to IDestructuringElement.
