[Feature Request] Handle remote inputs

We can make support the equivalent of the "Remote" functionality, as seen in HomeKit for example. Below is a screenshot from Reddit of what this looks like:

We can hook VPADRead and do something like this:

DECL_FUNCTION(int32_t, VPADRead, VPADChan chan, VPADStatus *buffers, uint32_t count, VPADReadError *outError) {
    int result = real_VPADRead(chan, buffers, count, outError);
    if(inject) {
        inject = false;
        buffers->hold = VPAD_BUTTON_A; // "A"
    }
    return result;
}

This will be for the later versions of Ristretto.
