Nionswift-instrumentation

-------------------
- Add console startup component to define stem_controller.
- Fix 161. Ensures proper scan after low level changes.
- Allow enabled channels to be set with frame parameters.
- Fix issue where acquisition control being set past last index.
- Begin work on new acquisition API (work in progress).
- Python 3.12 compatibility.

-------------------
- Fix issues with intermittent errors during synchronized acquisition.
- Fix 13. Scan recorder allows limited-only-by-memory frame count on scan devices.
- Fix 160. Introduce RecordingTask to allow synchronization of recording with other tasks.
- Eliminate special crop region on summed camera acquisition (EELS). Crop region now determined by camera readout area.
- Many improvements to improve ability to replace default scan device; work in progress.
- Simplify acquisition panel slightly (radio button to select mode); work in progress.
- Improvements to metadata handling during acquisition; work in progress.
- Fix 1D ramp acquisition using FOV; add ability to control rotation, too.
- Raise max scan size to 16384x16384 and correctly reduce it when required.
- Performance improvements (latency and frame rate).
- Performance improvements (scan recorder).
- Add Python 3.11 support. Drop 3.8. This will be the last Python 3.9 release, too.
- Fix some issues with subscan handling during synchronized acquisition.

-------------------
- Fix 151. Properly calibrate subscan/line-scan during synchronized acquisition.
- Improve handling of partial acquisition, directing data to desired data item.
- Fix more acquisition graphic edge cases: graphics only on enabled context displays.
- Fix issue where acquisition graphics would not appear on new channels.

-------------------
- Fix sync issue with SI (prep scan after camera stopped).
- Require scan_module (scan device and settings) rather than scan_device to be registered.
- Improve progress bars for 1D line scans.
- Only remove graphics from active acquisition data items (fix 127).
- Enable graphics properly when switching projects (fix 133).
- Only invalidate context field of view, rotation, or center changes (fix 140).
- Retain probe position when disabling and re-enabling (fix 139).
- Check channel states for changes before rebuilding thumbnails to avoid flashing.
- Allow scan modules to supply their own control panel UI.
- Make fov_size_nm be a computed property representing fov with aspect ratio applied.
- Add pixel_size_nm and subscan_pixel_size_nm computed properties to frame parameters.
- Handle scan data calibrations when scan data is 1D. Pass through 3D.
- Add channel_indexes_enabled to frame parameters for future use.
- Enable support for Python 3.11.

-------------------
- Replace flyback_pixels property with calculate_flyback_pixels method.
- Change 2D ramp (tableau) to use relative control values, like 1D ramp.
- Fix regression in multiple shift EELS acquisition.
- Ensure live view calibrations are correct during synchronized acquisition.

-------------------
- Drift correction improvements, simplified UI. Work in progress.
- Performance and reliability improvements.
