v1.2.0

• feat: new optional attribute anchored-to-id to specify where the panel should attach to
  • By default, when no anchor is specified, the panel will continue to be attached to the connected input.
  • The anchor element can also be passed in programmatically when calling setInputRef as an optional second parameter.
• fix: don't try to remove event listeners on disconnect if no input was connected
• fix: export all types from main entry point and provide an exports field in package.json
