Pyerrors

Added
- Vectorized `gamma_method` added which can be applied to lists or arrays of pyerrors objects.
- Wrapper for numerical integration of `Obs` valued functions with `Obs` valued intervals.
- Bootstrap import and export added.
- `matmul` overloaded for `Corr` class.
- More options for initializing `Corr` objects added.
- General Hadrons hdf5 reader added.
- New variant of second_derivative.
- CObs formatting added.
- Comparisons for `Corr` class added.

Changed
- support for python<3.8 was dropped and dependencies were updated.

Fixed
- Another bug appearing in an edge case of `_compute_drho` fixed.

Fixed
- `input.pandas` can now deal with columns that only have `None` entries.
- Bug in f-string conversion of `Obs` fixed.
- Bug in edge case of `_compute_drho` fixed.
- Several numpy 1.25 deprecations fixed.

Added
- `pyerrors` can now deal with replica with different gapsizes.
- String formatting method for `Obs` added.
- `t0` can now be extracted from hadrons files.
- `w0` can now be extracted from openQCD files.
- `pandas` SQL export can now deal with `None` entries in columns with `pyerrors` datatypes.


Fixed
- `dobs` submodule is now correctly imported.
- Bug in merging of `Obs` fixed.
- Bug in `rapidjson` dict output fixed.
- String conversion of `Obs` can now handle special `dvalue`s
- Bug in sfcf name sorting fixed.

Added
- Alternative way of specifying priors in `least_squares` added.
- Correlated fits now also work with priors.
- Lists of `Obs` can now be serialized and deserialized in pandas.to_sql
- `print_config` function for debugging purposes added.
- `Corr.show` can now visualize results of combined fits.

Changed
- Fit routines refactored and simplified.
- sfcf input routines refactored.
- drho is not automatically computed for all windows in the automatic windowing procedure. This change speeds up the `gamma_method` for very long Monte Carlo histories.
- `__slots__` added to `Corr` class.

Added
- The fit module now has a new interface to deal with combined fits.
- `pyerrors` wrapper for matplotlib `errorbar` method added for `Obs` valued lists/arrays.
- roots module can now determine roots of multi parameter `Obs` valued functions.

Fixed
- Bug in treatment of error propagation of non-overlapping configurations fixed.
- `Corr.symmetric` can now deal with `None` entries.
- Fix in `ms5_xsf` input routines.
- Bug in `dobs` output format fixed.
