Python 3.13 and an sweights fix

Python 3.13 support and an adjustable tolerance in the sweights calculation function

Python 3.12

Version 0.8.1

---

• Add support for Python 3.12, drop support for Python 3.8
• Improved support for zfit 0.20+

Thanks to @MoritzNeuberger for finding and proposing a hypothesis test fix.

Python 3.11 support

Upgrade to Python 3.11, removal of 3.7

fix constraint toy generation

Version 0.6.1

---

• fix toy generation with constraints
• minor changes with docs

Multidimensional and binned models

Version 0.6.0

---

• Upgrade to Python 3.10 and zfit >= 0.10.0
• Enhanced speed toy limit calculation
• Add multidimensionl PDF support
• Add support for binned data and models

Python 3.9 support

Upgrade to Python 3.9 and drop support for 3.6

0.4.0

Upgrade API to use create_new to make sure that the losses are comparable. Compatible with zfit 0.6.4+

0.3.1

• sPlot: Increase the tolerance of the sanity check from 1e-3 to 5e-2, if above the tolerance a ModelNotFittedToData
  exception is raised. In addition if the the check is above the 5e-3 tolerance a warning message is printed.

0.3.0

• New documentation style
• hepstats can now do hypothesis tests, and compute upper limits and confidence intervals for counting analysis
• Progess bars are used to see the progression of the generation of the toys

0.2.5

• ConfidenceInterval can compute Feldman and Cousin intervals with boundaries (i.e qtilde=True)
• AsymptoticCalculator asymov weights are now scaled to the number of entries in dataset from loss function if the loss is not extended
• hepstats.hypotests can now be used even if there is no nuisances. The pll function in utils/fit/diverse.py had to be modified such that if there are no nuisances, the pll function returns the value of the loss function.
• add notebooks demos for FC intervals with the FrequentistCalculator and AsymptoticCalculator.
• add warnings when multiple roots are found in ConfidenceInterval
• move toys .yml files from notebook to notebook/toys
