Reparameterize hollow_cylinder

Description

hollow cylinder currently uses R_core and R_shell where R_shell is the outer radius. This makes fitting, particularly with polydispersity problematic as R_shell can then go below R_core (or the distribution gets cut in odd way). Most other core shell models are parameterized as a R_core and thickness of shell.

Note that doing this will break saved projects using the old parameters unless we do something special.

original hollow_cylinder replaced by new version where parameters are now core radius and shell thickness, not outer radius and core radius.

Yes this will break any previously saved models.
