Retire `companies$company_id`

Relates to #7

This PR retires the dataset inst/extdata/deprecated/*companies.csv.gz because we need that place for another *companies.csv.gz dataset that is about to be deprecated. This comes with a warning -- which is only exposed when the user's version of tiltIndicator is old enough to expect the column companies$company_id -- which we now retire.

Warning message:
Using data that is incompatible with your version of tiltIndicator.
✖ Old titlIndicator used `company_id` but it's now retired.
ℹ Upgrade titlIndicator to use new data with `companies_id`.
