* Added full support for the following LabOne modules (no need to fallback to `zhinst.core`):
* Impedance Module
* Precompensation Advisor Module
* Introduced new base exception class `zhinst.toolkit.exceptions.ToolkitError`, deriving from `RuntimeError`.
* Changed some `RuntimeError` exceptions to `ToolkitError`.
* Added `find_zsync_worker_port()` to `PQSC` device class.
The function can be used to find the ID of the PQSC ZSync port connected to a given device.
* Added `session` property to `BaseInstrument`. This enables getting the given `Session` from the instrument.
* Changed SHFQA node `qachannels/*/oscs/0/freq` value range from (-500e6 Hz, 500e6 Hz) to (-1e9 Hz, 1e9 Hz). Out-of-range values now rounds
to (-1e9 Hz, 1e9 Hz). The functionality is changed to be consistent with LabOne UI.
* Improved verbosity of the error message when invalid attributes of `CommandTable.header` and `CommandTable.table` are used.
* Fix issue with downloading waveforms from the device. This issue prevented indexes larger than 9 to be read from the device.
