read bits off by 4 bits

[ehiverson]

In read():
The correct way to get the data is in the upper 12 bits, not the lower:
uint16_t result = (((((uint16_t)high_byte) << 8) | ((uint16_t)low_byte)) & 0xFFF0) >>4;

In readTemperatureConverted():
Similary, use
uint16_t raw = (((((uint16_t)high_byte) << 8) | ((uint16_t)low_byte)) & 0xFF10) >>7;
as temperature is in the upper 9 bits.
