A simple driver for the TVOC (Total Volatile Organic Compounds)
sensor from Aosong: AGS02MA
Steps in reading the VOC sensor value over i2c:
1. Read 5 bytes from the register `AGS02MA_TVOC_READ_REG` [0x00]
2. The first 4 bytes are taken as the big endian sensor data with final
byte being the CRC
3. The CRC is verified and the value is returned over an
`IIO_CHAN_INFO_RAW` channel as percents
Tested on Raspberry Pi Zero 2W
