This is most probably the result of a copy paste error. All vendor documentation for SI7021 (e.g. https://www.silabs.com/documents/public/data-sheets/Si7021-A20.pdf) points to 21 and it actually only works when adapted to 0x15 (=21).

HTU21D sensor class lacked the method `get_report_time_delta` invoked
during watermark control loops. This short fix simply adds that method
in, calling the `self.report_time` attribute created during class
construction.
