ENH: add identity_map_conversion as the noconvert default
requested to merge rhiannon.udall/bilby_pipe:feature/add-identity-function-compatibility into master
This maps to the MR bilby!1264 (merged) in the main bilby library. The help statements for bilby_pipe currently claim that passing "noconvert" will result in no conversion function being applied, which is not presently true. This function aligns behavior with the help statements.
