Efficiency & Leniency

• The default interval's been changed again to be LESS efficient, because I've done some magic tricks to decrease CPU usage further, and CPU usage was already really low.
• Caps Lock state is checked only every 500ms now
• A per-device cooldown been introduced when failing due to the infamous exclusive access error
• When a super specific error (that still indicates a success) which I've only seen caused when using Karabiner is detected, any other devices will be skipped
• Only the first LED will be enumerated for a given device
• CPU usage should be somewhat reduced now if you use Karabiner-Elements. Your CPU usage for netcaps WILL ALWAYS be better, though, if you disable Karabiner's virtual HID device. The peak CPU usage I've gotten WITH Karabiner on this release is ~10%. Without, it's around 6%.

Future: Don't re-enumerate duplicate devices maybe or maybe not depending on if I can be bothered.
