Build NOTE: use of unexported objects

[jacobvjk]

Unexported objects imported by ':::' calls:
    ‘r2dii.plot:::abort_if_missing_names’
    ‘r2dii.plot:::abort_if_unknown_values’
    See the note in ?`:::` about the use of this operator.

@jdhoffa @MonikaFu maybe we can either export these functions in r2dii.plot or put them elsewhere to avoid duplication and sketchy dependencies?

[jdhoffa]

These functions are pretty simple (i don't think they warrant a whole new package).
I would just write them out again in this package and maintain them here

[MonikaFu]

I agree with Jackson. Probably the best solution as they are not the core functionality of r2dii.plot but helper functions.
