Readme: Attempt to switch from md to rst

Adding the type annotation to setup.py didn't seem to help. Lets see if
restructured text renders better than md.

 Program to read eCO_2 and TVOC from the [SGP30 sensor](https://www.sensirion.com/fileadmin/user_upload/customers/sensirion/Dokumente/9_Gas_Sensors/Sensirion_Gas_Sensors_SGP30_Datasheet_EN.pdf). Based on the smbus2 i2c library for ease of use.

+Features that are known to be missing (listing in rough order of importance):
+---------------------------
 * Fix python3 compatibility.
 * The handing of baseline values are not that great, it should probably be up to the end user to save and restore them as needed.
 * Write doc-strings for all or at least most methods.
 * reading raw-values.
 * A more "driver like" class that took care of all chip identification, polling intervals store baseline and so on.
 
+Hardware notices:
+-----------------
 If you have the AdaFruit board with built in level shifters and voltage regulator it is should work if you just plug in [SDA to pin 3, SCL to pin 5, VCC to pin 17 and GND to pin 20](https://pinout.xyz/pinout/i2c). You should then be able to find the SGP30 an address 0x58 using `i2cdetect -y 1`. If you get an error message  you probbably need to enable i2c in the kernel using  [`raspi-config` and reboot](https://learn.sparkfun.com/tutorials/raspberry-pi-spi-and-i2c-tutorial)
