v2.5.5

This minor release changes the convention used for the $h_{T3}$ HQET form factor from the one of arXiv:1309.0301 to the one of arXiv:1703.05330. This fixes a bug in the implementation of the from factors from arXiv:1908.09398 (which use the convention of arXiv:1703.05330).

In addition, recent LHCb measurements of RD and RD* have been added (thanks to @MJKirk) and the flavio.plots.likelihood_contour_data function has received support for log scale grids.
