This will implement the interface with:
- The MS5637 temperature and pressure sensor
- The HYT-271 temperature and humidity sensor
This library assumes that the user has already included the Wire library.
object.pollMS5637() - void function. Reads MS5637 and updates object variables.
object.pollHYT271() - void function. Read IST HYT-271 and updates object variables.
object.initialise() - does what it says on the tin. Only required for MS5637.
