Update to arduino-esp32 v2.0.3

[Lukaswnd]

hi, due to some changes in the arduino-esp32 directories and including paths, Smartmatrix is currently not compatible with arduino-esp32 v2.0.0 or greater and thereby with platformio: platform-espressif32 (arduino framework) v4.0.0.
I found the following fork, which fixes the issue. Im not that great with git, but somebody else might create a pull request.
The fork is only 4 commits ahead, so it shouldn't be that hard.

Thanks for this fix, I started out trying to compile the code today for the first time in months and was stuck, this got me going again.

For those stumbling upon this, the following has to be added to

SmartMatrix/src/esp32_i2s_parallel.c

#include "soc/gpio_periph.h"
#include "esp32-hal.h"
#include "hal/gpio_types.h"

I can acknowledge that this change in particular fixes the problem.
