Add the Elecrow CrowPanel 7.0" as a third board, and take the packages and the add-on from Gitea (0.2.93)

A board file for the Elecrow CrowPanel 7.0" (DIS08070H, ESP32-S3-WROOM-1-N4R8): 800x480 through mipi_rgb, GT911 on the
ESP32-S3's USB pins (elecrow_usb_phy.h frees them, behind a flag only this board sets), the Guition's vertical sizes
across a wider page, no rotation. Its 4 MB of flash take the CYD's budget: a partition table of the component's
(smart_display: partitions: 4mb_wide_slots, 1,984 KB slots), the icon fonts at 2 bits a pixel and the TLS client only
bring the firmware to 1,865,440 bytes, 91.8 % of a slot, with camera images kept. docs/ELECROW.md has the numbers and
the trade.

The add-on reads a large board's name from the type sensor's value, the editor offers the board under New screen and
draws the wide preview, tools/check.sh builds it with the budget, render_topbar and capture_ui take the panel's size.
Firmware 0.2.79; the CYD image is unchanged (1,633,760 bytes).

This fork builds from gittea.trippedonmy.name/Xandrossian/homeassistant_espscreen: the packages, the fonts, the
component and the add-on repository point there instead of GitHub.
