ripc 0.3.0

Restructured API calls so that ipc_get() is more robust by defaulting to requesting a CSV return from the API rather than JSON, allowing for simpler cleaning in all ipc_get_...() functions.
Allow return_format to be specified as GeoJSON for ipc_get_areas(), directly loading in an sf object.
Improved the cleaning of ipc_get_population() nested JSONs to be more robust to changes in the API.
Set R-CMD-check GitHub Action to run weekly to check for changes to the API, since all function examples are re-run during the check.

ripc 0.2.1

Improved ipc_get_population() to deal with missing areas data when it is removed from the API.
Fixed assert_start_end() so it correctly tests start and end parameters without generating an error.
Fixed ipc_get() to initially read all numeric vectors as character in as some errors were created in nested data frames that only contained integers.
Ensured that all ipg_get_...() functions returned properly parsed numeric columns and fixed some unnesting data frames in ipc_get_areas().

Changed anl_id column to always be analysis_id.
Implemented optional tidy_df parameter so user can choose to receive data as returned direct from the API, and fully document cleaning in each function.
Updated function documentation and vignettes to match the new simplified and advanced API endpoints.
Improved date wrangling to avoid generating warnings for rows without explicit dates.
Added examples and explicit return values for all functions.
Added links to the IPC-CH API and GitHub repository to DESCRIPTION.
Memoisation functionality dropped to meet CRAN requirements.
Initial CRAN release.

Adjusted create_date_columns() to avoid warnings when parsing missing values in the period_dates column.

Added areas output back to ipc_get_populations() as it was added back to the IPC API

Fixed ipc_get_populations() by removing calculations for the areas data frame which was removed from the API

ipc_get_icons() and ipc_get_populations() changed so all date columns converted from character to date explicitly.

ipc_get_analyses() and ipc_get_country() changed to use anl_id.
ipc_get() memoised to avoid repeated calls to the API. Now all ipc_get_...() functions are cached in a session.
