Smelli

This minor release updates the covariance matrices in `smelli` using the input parameters of `flavio v2.6.1` (thanks to alekssmolkovic)

This minor release updates `smelli` to support `flavio v2.6.1`.

This release updates `smelli` to `flavio v2.5.4`.

In particular, all covariance matrices and the CKM scheme have been updated using the inputs from `flavio v2.5.4`.

New observables
- $b\to d\ell\ell$ observables used in [arXiv:2212.10497](https://arxiv.org/abs/2212.10497) (thanks to alekssmolkovic)
- $D$ meson charged current decays (thanks MJKirk)

New measurements
- $R_{K_S}$ and $R_{K^{*+}}$ measured by LHCb in 2021 (thanks nsahoo)
- $R_K$ and $R_{K^*}$ measured by LHCb in 2022
- $B_s\to\mu\mu$ combination of LHCb, ATLAS, and CMS measurement from [arXiv:2212.10497](https://arxiv.org/abs/2212.10497)

Updated measurements
- `K+->pinunu NA62 2019` updated to `K+->pinunu NA62 2021`
- `Ft(0+) Hardy/Towner 2014` updated to `Ft(0+) Hardy/Towner 2020` (thanks MJKirk)
- `PDG 2015` updated to `PDG 2022` (thanks MJKirk)

This minor release updates the Bs→φμμ angular observables to FL, S3, S4, and S7 measured recently by LHCb ([arXiv:2107.13428](https://arxiv.org/abs/2107.13428)).

This minor release adds b→sll observables with q² bins below 1 GeV². The set of all b→sll observables in this release is equal to the one used in [arXiv:2103.13370](https://arxiv.org/abs/2103.13370).

This release adds several new observables and measurements.

New observables
- The B0->K\*mumu and B+->K*mumu angular observables P3, P6, and P8
- The Bs->mumu effective lifetime
- mu-e conversion in nuclei (thanks hoodyn)
- BR(B0->ee) and BR(Bs->ee) (thanks to hoodyn)

New measurements
- The 2021 LHCb measurement of BR(Bs->mumu) combined with ATLAS and CMS data
