Dvg-pyqtgraph-threadsafe

------------------
Code quality improvements:

* Using ``qtpy`` library instead of my own Qt5/6 mechanism
* Using f-strings
* Extended API and docstrings, like on `PlotManager`.
* Arguments `linked_curves` and `linked_plots` are hinted as `Sequence` instead
of as `List`

Added support:

* Support for Numpy 2.0

------------------
* Raise `ImportError` instead of general `Exception`

------------------
* Added link to notes on use-case: DAQ

------------------
* Minor edit: Using explicit arguments `x` and `y` to set the curve data and set
the flag `skipFiniteCheck=True`. Both save (marginal) CPU time.

------------------
* Bug fix: Snapshot creation checks if internal buffer is of type RingBuffer and
casts to numpy.ndarray. This resolves an intermittent error where the
`isfinite` boolean return array was operating as mask on the RingBuffer, which
fails. The boolean return array now always operates on numpy.ndarray.
* Fix for external bug in `paintGL` of `pyqtgraph\graphicsItems\PlotCurveItem.py`:
Added explicit check to ensure that the curve is only drawn when it has more
than 1 point.
* Added benchmark running `python=3.10` and `pyqtgraph==0.13.1`

------------------
* Fixed bug when using PyQt6: `QMessageBox.Yes` --> `QMessageBox.StandardButton.Yes`
