Fix delay value

When not using 12 bit resolution, we don't actually need a delay of 750-1000ms.

Measurement: -2045°C

How was this possible? :)

Add push mode

Right now we're using pull mode to publish data (we expose a variable and the client pulls the data).

For the water temperature version, we should switch to push mode (the photon or electron publishes a temperature measurement event).

Energy Management

The electron should use very little energy.

• Turn itself off after a measurement
• Wake up when necessary

I'm not sure if waking up is supported through a builtin clock, or whether we need to use the wakeup pin with an external clock.

Blocked by #2.

Handle CRC failures

Sometimes the data returned looks like this:

Data = ff ff ff ff ff ff ff ff ff CRC = c9
Data = ff ff ff ff ff ff ff ff ff CRC = c9
Data = ff ff ff ff ff ff ff ff ff CRC = c9
Data = ff ff ff ff ff ff ff ff ff CRC = c9

Handle it.
