* Add optional `integration_length` argument to the `configure_weighted_integration` function of the SHFQA / SHFQC. If the argument is set to `None` (default value), the integration length is determined by the length of the first integration weights vector, which is the same behavior as in the previous versions to ensure backwards-compatibility.
* Fix typehints for `convert_awg_waveform` to correctly hint the two optional arguments `wave2` and `markers`
* Move feedback model into separate package `zhinst-timing-models`. The new package is reimported so the imports can stay the same. But its recommended to use the new package directly.
