[Feature Request] LED configuration

[flpcstrike]

Description

For someone like me which lacks programing skills and could not manage to edit or configure the lights with msys, having basic LED configuration would be a really nice QoL feature to have in the online configurator.

For example:
Solid colour selection without any crazy rgb matrix effects. (Locking the keyboard to a single colour.)
Selection of which lights to enable/disable. (Like the side lights on gmmk models.)
Caps lock colour change option when its enabled.
