This PR allows the Brute filter parameters to be configured rather than using fixed constants. It also tweaks the presets to take advantage of these new options: o3: level=1, lines=3 (fractionally worse/faster) o4: level=1, lines=4 (same as before) o5: level=4, lines=4 (fractionally better/slower) o6: level=5, lines=8 (slightly better/slower) The parameters can be explicitly set in both the API and the CLI.
