requirements.txt does not have versions

I tried to run rdplot with an venv using python 3.7 and installing requirements (in src/rdplot) using pip. it could open the application, but it crashed when selecting curves. Needed to downgrade matplotlib to 3.2.2.
Maybe we should add the version information to the requirements.txt. Ideally this should then match whatever exact versions are used to build pipx or windows installer packages.

I think this is only true for matplotlib. In setup.py matplotlib=3.4.2 is required and that should work as well. IMHO, we could add the version number for matplotlib.
Can you just check, whether 3.4.2 also works for you?

For me rdplot also crashes when selecting more than one curve, but I do not think the problem is related to the matplotlib version. The error message I get is:TypeError: setRowCount(self, rows: int): argument 1 has unexpected type 'float'

RDPlot/src/rdplot/Widgets/MainWindow.py

Line 566 in 443cdf1

self.tableWidget.setRowCount(len(plot_data_collection)/len(config))

This can easily be fixed by a typecast to int().

However, tikzplotlib is currently not compatible with matplotlib>=3.8.0 as some private methods from matplotlib which tikzplotlib uses have been deleted.
