Add support for Sensirion SEN5X (SEN55, SEN54, SEN50) environmental sensors for PM2.5, NOx, and more

[sg1888]

Describe the problem you have/What new integration you would like

I'd like you to add support for the newest line of PM sensors from Sensirion - the SEN5x series.

Please describe your use case for this integration and alternatives you've tried:

Sensirion has released their newest line of air quality sensors, the SEN5x series. These sensors combine the best features of many of their other sensors supported on ESPHome, including the SPS30, SHT30, and more.

These sensors are also cheaper than Sensirion's SPS30 PM sensor (~$34 for the SEN54 vs. $55 for the SPS30 on DigiKey). I suspect most users will ultimately gravitate to the the SEN5x series as it offers more bang for the buck.

Adding this sensor would be a great addition to ESPHome!

I have a pull request ready to submit but it relies on https://github.com/esphome/esphome/pull/3374 therefore I didn't submit it yet.

The current state of documentation is at https://github.com/martgras/esphome-docs/blob/sen5x/components/sensor/sen5x.rst

Please give this a try to test my code:
