Features

• Add support for Bulk 1.0 operations of "create", "update", "upsert", "delete" and "hardDelete"
• Bulk 2.0 operations, by default, now return a single tbl_df containing all
  of the successful records, error records, and unprocessed records
• Created internal functions that explicity call each API for an operation. For
  example, sf_create() routes into sf_create_soap(), sf_create_rest(), and
  sf_bulk_operation().
