More informative error messages

[pitkant]

The following query does not return any error message:

> eurostat::get_eurostat("road_go_ia_rc", filters=list(unit = c("THS_T")), cache = FALSE)
Error in get_eurostat_json(id, filters, type, lang, stringsAsFactors,  : 

Obviously it should output a message that would contain the following information as parsed text:

{ "error": [{"status": 413,"id": 413,"label": "EXTRACTION_TOO_BIG: The requested extraction is too big, estimated 5101056 rows, max authorised is 5000000, please change your filters to reduce the extraction size"}]}

> eurostat::get_eurostat("road_go_ia_rc2", filters=list(unit = c("THS_T")), cache = FALSE)
Error in get_eurostat_json(id, filters, type, lang, stringsAsFactors,  : 
  HTTP status: 404 (Not found)
  Error id: 100 (No results found)
  Error label from API: ERR_NOT_FOUND_4: ROAD_GO_IA_RC2 (DATA_SET:ESTAT,1.0) is not available for dissemination.

The package currently handles "Error messages returned in case of invalid queries" but it should account for all other types of error messages as well.
