Please add the epaper display from Goodisplay in size 7.5in to the supported epaper's

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

Currently there's a lot of epaper displays from Waveshare supported, but also some Goodisplays. the currently non-listed 7.5 in epaper BW screen should be added.

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

I've tried all the variants from waveshare, but they seem not to refresh within the supported 3ms on a ESP32-C3.

**Additional context**

You can find the description and all details on the display at the manufacturer here:
https://www.good-display.com/product/396.html

Start with the Good-Display product page linked in the issue and compare its 7.5-inch BW display details with the currently supported Waveshare and Goodisplay displays. Confirm what is needed for support and verify that the display refreshes on the stated ESP32-C3 use case; the issue does not name repository files or tests.
