Fix(#78): replaced internal function reference to external

[andybeet]

Justification

survdat had internal functions that were needed for data analysis outside of the package. These were made external functions in the survdat package. As a consequence all reference to them here needed to change from using ::: to ::. This PR makes these changes

Fixes #78

@MGrezlik. Your Rpath scripts that used survdat:::post_strat (three colons), will also need to be changed to use ::, (2 colons)

@andybeet Thanks for the reminder. I'll put an issue in that repo. Once we work through all the clam survey issues in the survdat repo I will want to do a fresh pull for the Rpath models
