DIY Screen support

[monzsca]

Hello, after finding this project, I decided to get a NSPanel. Very happy with the results and ease of installation. Since the hardware seemed relatively simple, I decided to try making one with a larger screen. So I acquired a 5" Nextion (nx8048p050-011c) display and give it a try.

I was able to get it working with just a few config/code changes. The TFT file needs to be modified for the larger screen, which isn't difficult, just time consuming. I'm using this with a ESP32-WROVER-E because it has psram, though I was able to get it working wiht a ESP32-WROOM by removing the psram option in the yaml file, this caused OTA TFT upload to not work, but seemed to work ok otherwise.

I was thinking this software could be easily modified to provide both an easy install for NSPanels, but also add the ability to provide configuration that overrides defaults for DIY panels, such as gpio assignments, turn features on and off, etc. In my case, I needed to change gpio pins for the tx/rx for the display and remove gpio settings for psram so it defaulted to the default. Features like buttons, relays and temperature I'm simply ignoring. They also make 7" and 10.1" screens, so there's quite a bit of potential to support many custom screens.
