Add support for the ILI9342C

[jessebraham]

First off, thank you for your work on this project! I had previously attempted to implement this driver from scratch and lost motivation, however it was trivial to implement in this repository.

The ILI9342C is used by the ESP32-S3-BOX, which is what I used for verification. Based on some very simple testing this seems to be working as intended.

Some notes on this implementation:

• Very similar to the current ili9486 model, with some small tweaks
• I've based the initialization routine on this driver; I'm not certain if everything has been covered, but it is funcional
• Currently only supports Rgb565; I did try Rgb666 however the colours were not correct, and I did not spend much time trying to troubleshoot
• For whatever reason the width/height values needed to be the reverse of what I'd normally expect (smaller then larger), however this seems to be how this display works

If you'd like anything changed or added please let me know!

Thank you! I'll have a closer look in a day or two.
