and remove the old cache
BULK DOWNLOAD ADDED: the function
ct_get_bulk has been added. It enables the use of the bulk
download facility from Comtrade.
Please see the vignette https://docs.ropensci.org/comtradr/articles/bulk_files.html for details
Caching Functionality: Implemented enhanced caching features, and added a dedicated vignette explaining caching concepts. Environment variables allow for configuration of some caching features.
Functionality Updates: Major updates to key
functions such as ct_get_data and
ct_get_ref_table, including parameter adjustments and
usability improvements, mostly checks for all important parameters
before the request is send out.

Update the country package data, to stay up to date with the

In func ct_search(), improve error messaging when an

HTML (as opposed to json data). (#27).
In func ct_country_lookup(), remove NA
inputs from multi-country lookups (previously NA was being
stringified and included in the pipe-separated regex lookup).
