fedstatAPIr 1.1.0

Breaking changes

Unspecified filter fields with multiple possible values now produce an informative error instead of silently selecting all values. Use "*" to explicitly select all values for a filter field. Single-value-only filters are still auto-selected. The error message lists all unspecified fields with an example of how to fix them.
Minimum R version raised from 2.10 to 3.5.0 (required by serialized data format).

EMISS moved data download endpoint from /indicator/data.do to /indicator/downloadData.do. All download functions updated automatically – no user code changes required.
Fixed pre-existing typo ObsValues -> ObsValue in fedstat_parse_sdmx_to_table() that caused the numeric parsing safety check to silently never fire.

fedstat_data_load_with_filters() now automatically retries the full download pipeline (GET + filter + POST) on transient failures, re-fetching a fresh CSRF token on each attempt.
CSRF token is automatically extracted from the indicator page during fedstat_get_data_ids() and passed through the pipe chain via data.frame attributes.
HTTP session (cookies) are now persisted between the page GET and data POST via httr::handle(), also passed as a data.frame attribute.
Improved error messages: specific diagnostics for HTTP 302 (rejected filters), 403 (anti-bot), 503 (overloaded), HTML-instead-of-data responses, and CSRF token failures.
fedstat_parse_sdmx_to_table() now detects HTML error pages before attempting XML parsing, giving clearer error messages.

Honest User-Agent header (fedstatAPIr/1.1.0) is now set by default. Users can override via ... arguments or httr::set_config().
fedstat_post_data_ids_filtered() no longer retries POST requests internally (CSRF tokens are single-use). Use the wrapper fedstat_data_load_with_filters() for automatic retries, or re-run from fedstat_get_data_ids() when using individual functions.
Refreshed fedstat_indicators_names_database (5224 indicators, new schema: department, group, id, title, hidden).

removed all dependencies except httr, jsonlite, xml2, readsdmx, magrittr, utils, methods, data.table for much easier installation
backend of all functions rewritten in data.table
new features: it’s now possible to load database full dictionary from sdmx by providing new argument return_type to fedstat_parse_sdmx_to_table, obervation value in data is now parsed from character to numeric type automatically
fixed some old problems with russian encoding data fields and filters by converting to UTF-8
removed all functions related to automatic data update checks (fedstat_check_data_update, fedstat_prepare_reference_data_for_check_data_update), were experemental, too complex and not a main part of a package
removed function fedstat_get_data_ids_special_cases_handle, no longer needed due to change of upstream API
new function fedstat_indicator_info - allows to update database of all indicators by user
user interface to the package (except deleted functions) has not changed, some non-significant default arguments have been changed or added
