sensor measurements are only executed once

The Method _configure_sensor() writes register ctrl_meas (0x74) two times:

• first in line 91 with value 0x24. The comment says oversampling x4. According to my datasheet value 0x24 is oversamling x1. Oversampling x4 would be 0x6d.

• second in line 94, overwriting the value in line 91 which probably can be removed. But the register ctrl_meas is only written in the initial configuration, so the ambient values never gets updated. _configure_sensor() should probably be also called after every read.

The humdity oversampling in line 88 also doesn't match the comment.
