Disable hardware pulsing to allow running without root

Browse Source 
Set options.disable_hardware_pulsing = True in display_manager._setup_matrix.

This corresponds to the --led-no-hardware-pulse flag for the rgbmatrix library.

Disabling hardware pulsing removes the need for root privileges, allowing the script to run as the regular user (ledpi).

This aims to resolve the permission issues encountered when trying to write stock logos to assets/stocks while running with sudo (which resulted in UID=1 instead of UID=0).
