RuntimeError: libmambapy.Pool has been moved to libmambapy.solver.libsolv.Database. The database contains functions to directly load packages, from a list or a repodata.json. High level functions such as libmambapy.load_subdir_in_database and libmambapy.load_installed_packages_in_database are also available to work with other Mamba objects and Context parameters.

I can reproduce these failures in the asv test suite with libmambapy=2.0.2
