Update Squareline Studio example to LVGL 9.1

[aliphys]

As described in #29 , SquareLine Studio now:

• Supports LVGL9.1
• Allows for export of the library/UI files

This PR modifies the existing squarelinestudio_lvgl_v8.ino sketch, in line with the updates made to SquareLine Studio to undo regressions. 🌟

Closes #29

[aliphys]

When compiling the squarelinestudio_lvgl.ino sketch new libraries/UI folder from Squareline Studio with LVGL9.1, there is an undefined reference to ui_init().

C:\Users\Ali Jahangiri\AppData\Local\Temp\arduino\sketches\13EED99990BB5BE14B654F6C77474EA5\sketch\objs.a(squarelinestudio_lvgl.ino.cpp.o): In function `setup':

I see that the following line is not changed between the previous version:

• Arduino_GigaDisplay/examples/lvgl/squarelinestudio_lvgl_v8/ui/src/ui.h

  Line 37 in de47486

  void ui_init(void);

• Arduino_GigaDisplay/examples/lvgl/squarelinestudio_lvgl/ui/src/ui.h

  Line 44 in d9d24d7

  void ui_init(void);

@leonardocavagnis can you advise on this?

[aliphys]

Following recommendations from @leonardocavagnis , the example now works. The UI folder must be located within the Arduino/libraries folder of the local installation, not the sketch itself.

[aliphys]

Example also works with LVGL 8.4 (so should not break existing code created previously )

[aliphys]

When comparing compilation time (Intel Core i7-1360P @ 2.20 GHz, 32 GB RAM, Windows 10) between LVGL8.4 and LVGL9.1: LVGL9,1 is about 60% slower.

LVGL Version	Compile 1 (m:s)	Compile 2 (m:s)	Compile 3 (m:s)
8.4	1:41	1:40	1:41
9.1	2:41	2:38	2:34

Between each run, the library cache was emptied by switching the board as described by @per1234 here.

Could possibly be improved by arduino/arduino-cli#2625

Does not cause any breaking changes. So we can continue with the PR.

Everything looks good!
