Pinned root_base missing migration to cfitsio441

Right now many new packages fail to render because they are built against the latest version of cfitsio (either directly, or transitively). This is 4.4.1.

However, this migration has not been backported to the pinned version(s) of root_base, resulting in a conflict.

This needs to be resolved upstream (in conda-forge) to free up many of the SCCB requests.
