Description
We have inner_split() methods for the automatic/default behaviour on how to make calibration spilts, but those are not accessible to the user. We still need a way to allow users to create splits beyond what inner_split() automatically does.
Our current thinking is to provide a helper function to make resampling objects that carry the calibration info, rather than opening up access to inner_split(). So basically, a different approach than #493.

Research direction
Start by reading the existing inner_split() methods and the discussion in issue #493. Determine how a helper for user-created calibration splits should construct resampling objects and preserve calibration information. Done means users can create splits beyond the automatic behavior without directly accessing inner_split().
