* Add must-install feature, so that a non-default handler can be the only handler consuming .text. * Provide a better panic message if `must-install` feature is enabled. Co-authored-by: Jane Lusby <jlusby42@gmail.com> * Bump version because new feature was added. * Convert must-install feature to auto-install to avoid negative features. * Add ability to manually install DefaultHandler (for when auto-install is disabled). * Ensure doctests pass when auto-install feature is disabled. * Integration tests now succeed without auto-install feature. * Add integration test for when auto-install feature is disabled. * Add auto-install feature testing to CI. * cargo fmt.
