finbif v0.9.0

NEW FEATURES

• New function finbif_update_cache can be used to update all the
  cached objects that have reached their expiration and are no longer
  valid.

• A restricted data API token can be explicitly declared via the
  restricted_api argument to finbif_occurrence.

• Cached data can use a database as a backend by passing a DBI
  database connection object to the package option
  finbif_cache_path.

• Cached data can be assigned a timeout by using a number (hours)
  instead of a logical value for the cache argument to finbif_
  functions or the package option finbif_use_cache.

• Record aggregations with finbif_occurrence can now be combined
  with multi-filter requests. Removing duplicate records or aggregate
  record combinations can be controlled with the duplicates argument
  and adding a column indicating the filter sets can be added with the
  filter_col argument.

BUG FIXES

• Fixed a bug causing an infinite recursion when determining page size
  during record download pagination.

• Fix bug triggered when using aggregation with some selected
  variables.

DEFUNCT

• Mapping utilities finland_map, breaks_xy, hist_xy and the plot
  method for finbif_occ objects are now defunct.

• User access to finbif_records and its classes and methods is now
  defunct.
