Added sea level pressure calculation helper function

README.md

This is a library for the Adafruit BME280 Humidity, Barometric Pressure + Temp sensor

Designed specifically to work with the Adafruit BME280 Breakout

These sensors use I2C or SPI to communicate, up to 4 pins are required to interface

Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!
