usb-thermometer: TEMPer1 and TEMPer1F

From Pete Chapman:

• Fixed poor precision for TEMPer1F (iProduct string "TEMPer1F_V1.3").

From Peter Vojtek:

The original version of pcsensor0.0.1 was located on this page. I took the source code and fixed following bug:

• temperatures below zero overflow: 254.3 C is displayed instead of -1.3 C, .

How to run it

1. clone this repository
2. $ sudo apt-get install libusb-dev
3. $ make
4. connect the thermometer
5. $ sudo ./pcsensor

The output looks like:

2014/10/30 07:00:36 Temperature 73.96F 23.31C
