Xypattern

- now correctly saves a file without background (subtract_background parameter false) when auto_bkg is set

- fixed inclusion of compiled smooth bruckner functions in wheels on linux and macos

- added feature to delete a range in a pattern
- added filename field in pattern, which contains complete filepath (name will still just hold the name)
- added transform_x function to modify the x-axis in place (will also update backgrounds)
- changed the auto background api, new usage:
python
pattern.auto_bkg = SmoothBrucknerBackground()
pattern.auto_bkg_roi = [10, 20]
pattern.auto_bkg = None will switch it off

- enable poetry versioning plugin during build, to hopefully work when installing with pypi

- fix constraints to also actually work with python 3.8

- provide packages for python 3.8 to 3.12
