Webauthn

**Changes:**

- Add new `credential_device_type` and `credential_backed_up` values to output from `verify_registration_response()` and `verify_authentication_response()` ([136](https://github.com/duo-labs/py_webauthn/pull/136))
- Add support for the new `"hybrid"` transport (the generalized, eventual successor to `"cable"`) ([137](https://github.com/duo-labs/py_webauthn/pull/137))

**Changes:**

- Restore the ability to pass more common bytes-like values for `bytes` fields, such as `str` values ([132](https://github.com/duo-labs/py_webauthn/pull/132))

**Changes:**

- Refine support for bytes-like inputs to comply with stricter mypy configurations ([130](https://github.com/duo-labs/py_webauthn/pull/130))

**Changes:**

- Fix authenticator data parsing to correctly parse extension data when present ([125](https://github.com/duo-labs/py_webauthn/pull/125))
- Add support for the new `"cable"` transport ([129](https://github.com/duo-labs/py_webauthn/pull/129))

**Changes:**

- Add support for `memoryviews` for `BytesLike` properties including `credential_public_key`, `authenticator_data`, etc...

**Changes:**

- Switch back from attrs + cattrs to **Pydantic** while preserving support for `bytes`-like values in subclasses of `WebAuthnBaseModel`.
