Structures RGBMatrix:Options and RGBLedMatrixOptions members are not ordered in the same way

[mick111]

In include/led-matrix.h and include/led-matrix-c.h, the members disable_hardware_pulsing, show_refresh_rate, and inverse_colors are not ordered in the same way:

• Before const char *led_rgb_sequence in C++ structure RGBMatrix:Options (lines 125-137 of led-matrix.h)
• After const char *panel_type in C structure RGBLedMatrixOptions (lines 143-149 of led-matrix-c.h)

That made this assert to fail in my fork:

static_assert(sizeof(rgb_matrix::RGBMatrix::Options) == sizeof(RGBLedMatrixOptions), "C and C++ out of sync");
