Findpeaks

* Improved implementation finding peaks in cases with small absolute variance 26 35 36
Thank you kohlert

* Bug is fixed in peakdetect
* Peakdetect 1.2 is used
* Newest scipy is used again
* Fix for bug in caerus

* code refactoring and cleaning by arvinnick
Thank you for the contribution!

* Fix for Issue 31
* Set scipy to version 1.11.4 because peakdetect breaks as it does not support importing fft and ifft directly from scipy.

* issue 29
* added interpolate_line1d, interpolate_line2d and interpolate_nans into imports during initialization

* fix for detection of valleys again
* fix for lee_sigma for parallel job
* catch error for plot persistence if not exist
* set the default limit back to None
* Fix for issue 27

This version can change the detection of peaks/valleys slightly in comparison to previous versions because it contains improved peak/valley detection fixes and some bug fixes.
