Flavio

This minor release adds missing `package_data` in `setup.py`.

In addition, the $B\to\ell\nu$ measurements have been updated (thanks to alekssmolkovic )

New observables
- The high-mass neutral current ($pp \to \ell \ell$) and charged current ($pp \to \ell \nu$) Drell-Yan differential cross-section predictions and experimental data as described in [arXiv:2212.10497](https://arxiv.org/abs/2212.10497) (thanks to alekssmolkovic and jsalko)
- LFV quarkonium decays as described in [arXiv:2207.10913](https://arxiv.org/abs/2207.10913) (thanks to micha-a-schmidt)
- Several $b\to d\ell\ell$ observables used in measurements by Belle and LHCb (thanks to alekssmolkovic)

New measurements
- $B_s\to \mu\mu$ measurement by CMS from 2022 and a combination with the LHCb and ATLAS measurements done in [arXiv:2212.10497](https://arxiv.org/abs/2212.10497)
- The new and update measurements of $R_K$ and $R_{K^*}$ by LHCb from 2022

New and updated input parameters
- $B_d$ and $B_s$ bag parameters for meson mixing as described in [arXiv:2212.10497](https://arxiv.org/abs/2212.10497)
- $B\to \pi$ form factors from [arXiv:2102.07233](https://arxiv.org/abs/2102.07233) (thanks to alekssmolkovic)

Bug fixes and code improvements
- Several probability distributions based on the Gamma distribution have been implemented in a more consistent way and previous issues have been fixed
- Several issues in the definition of the $B\to D$ and $B\to D^*$ HQET form factors have been fixed

New observables
- A large number of observables (decay widths and angular observables) of the decay Λ_b→Λ(1520)ll has been added, including two different form factor implementations (thanks to Felicia56)

Measurements
- The `LHCb B->ee 2020` measurement has been implemented using the Gaussian uncertainties provided in the LHCb paper instead of upper bounds, which allows it to be used in a `FastLikelihood` (thanks to alekssmolkovic)

Bug fixes
- In the computation of epsilon_K, an issue with the renormalization scales of quark masses has been resolved (thanks to MJKirk)
- An issue with labels in contour plots when using a `matplotlib` version >= 3.5.0 has been fixed (thanks to MJKirk)
- The complex phase in the CKM dependence of the K→πνν amplitude has been fixed
- Deprications in numpy that expired in numpy 1.23 and 1.24 have been fixed

This minor release adds the recent LHCb measurements of R(KS) and R(K*+) from [arXiv:2110.09501](https://arxiv.org/abs/2110.09501) (thanks to nsahoo).

This is a bug fix release that makes `flavio` compatible with the interface of `particle` v0.20.0.

This minor release adds the recent LHCb measurements of the B_s→φμμ angular observables FL, S3, S4, and S7 from [arXiv:2107.13428](https://arxiv.org/abs/2107.13428).
