Request: Add support for Chroma 74H+ display

[asdman384]

Hello!

First of all, thank you for the great work on GxEPD2, it’s been incredibly useful for e-paper label tags.

I’d like to request support for a new display model: Chroma 74H+.
Would it be possible to add support for this display in the modded library?

Additionally, I’d like to ask:
Is it possible to use an existing GxEPD2_750c_F19 class from GxEPD2 for the Chroma 74H+ just by changing the screen resolution (width and height), or are there deeper compatibility issues (e.g., controller differences, LUT timings, initialization commands) that would prevent this?

Thanks in advance for your help and for maintaining this great project!

I was able to display image using not modified GxEPD2_750c_Z08 class on Chroma 74H+
