AI Summary: Add a new MCP tool, `read_topic_frequencies`, to the Bagel server. This tool will calculate topic frequencies (time deltas between messages) for specified topics within a given time range. The implementation will closely mirror the existing `read_topic_messages` tool, but utilize a different reader factory and fewer arguments.

AI Summary: Create a new Dockerfile and Docker Compose service for processing PX4 ULog files using Bagel. This involves basing the Dockerfile on an Ubuntu image, installing the `pyulog` package using Poetry, and adding a new `px4` service to the `compose.yaml` file. The new service should allow users to access and process `.ulg` files within a Docker container.
