bigrquery 1.4.0

• bq_table_download() has been heavily refactored (#412):

  • It should now return the requested results, in full, in most situations.
    However, when there is a "row shortage", it throws an error instead of
    silently returning incomplete results.
  • The max_results argument has been deprecated in favor of n_max, which
    reflects what we actually do with this number and is consistent with the
    n_max argument elsewhere, e.g., readr::read_csv().
  • The default value of page_size is no longer fixed and, instead, is
    determined empirically. Users are strongly recommended to let bigrquery
    select page_size automatically, unless there's a specific reason to do
    otherwise.

• The BigQueryResult object gains a billing slot (@meztez, #423).

• collect.tbl_BigQueryConnection() honours the bigint field found in a connection object created with DBI::dbConnect() and passes bigint along to bq_table_download(). This improves support for 64-bit integers when reading BigQuery tables with dplyr syntax (@zoews, #439, #437).
