Reverts #6

Yep. Like that.

The integrity check looks like it is only a one-time power up thing:

so not something that is expected to happen sometime later in operation.

Also, the PR #6 code:

if self._buffer[2] & 0x01:

is checking the first bit of the third byte returned, which is the second byte of sensor data.

Tested for good measure:

pi@raspberrypi:~ $ python3 mprls_simpletest.py

(1008.0111705085358,)
(1007.9935763013558,)

runs forever.
