This release contains updates to all the dependencies including pySigma version bump to [v0.10.4](https://github.com/SigmaHQ/pySigma/releases/tag/v0.10.4). The pySigma v0.10.x release introduced **breaking changes** that also affects this backend.

In addition, backend options parsing for boolean values is fixed and a backend identifier, `loki`, is added to the `LogQLBackend` class to assist pySigma [autodiscovery feature](https://github.com/SigmaHQ/pySigma#autodiscovery-and-migration-of-backend-plugins) in uniquely identifying this backend while enumerating the list of available backends.
