Add a Joystick Slider default to just use whatever is set in core, or remove the setting entirely

Enabling the Joystick Selection Slider also requires you to make this setting choice, which enforces one (and only one) mode when you are not holding the jslider pin(s). This means that if you only have one pin (say assigned to LS) and select DP in the above selection, you can never switch to RS, because the current jslider addon will enforce either the held pin or options.modeDefault.

I propose either adding another option to the dropdown that is "just use whatever core is set to" (phrased better), which would let you change between DP and RS, in the above example, via hotkeys, or remove the configuration element entirely and just always default to whatever core is set to, as in asserting no override (unless the pin(s) are held).
