[Feature request] add support for coarse grained RTD3

[Yato202010]

by default envycontrol se fine grained RTD3 in hybrid mode but on my laptop fine grained is not available and require the use of coarse grained RTD3

i would be great to add this as a option which would be enable using a config file or a optional arguments

bellow is the change i used locally as a temp fix

MODESET_FINE_PM = '''# Automatically generated by EnvyControl
options nvidia-drm modeset=1
options nvidia "NVreg_DynamicPowerManagement=0x02"
'''

MODESET_COARSE_PM = '''# Automatically generated by EnvyControl
options nvidia-drm modeset=1
options nvidia "NVreg_DynamicPowerManagement=0x01"
'''

elif mode == 'hybrid':
        _cleanup()
        # Enable modeset for Nvidia driver
        choice = input('Enable RTD3 Power Management? (y/N): ').lower()
        if choice in yes:
            _create_file(UDEV_PM_PATH, UDEV_PM)
            choice = input('Use Fine Grained RTD3? (Y/n)').lower()
            if choice in yes:
                _create_file(MODESET_PATH, MODESET_FINE_PM)
            else:
                _create_file(MODESET_PATH, MODESET_COARSE_PM)
        else:
            _create_file(MODESET_PATH, MODESET_CONTENT)
        _rebuild_initramfs()
