Fix "discards qualifiers" compiler error (#253)

Browse Source 
GCC wouldn't compile because NeoPixelBus::CanShow() is declared const but IsReadyToUpdate() is not:

    NeoPixelBus.h:161:40: error: passing 'const NeoEsp8266DmaMethodBase<NeoEsp8266DmaSpeedWs2812x>' as 'this' argument of 'bool NeoEsp8266DmaMethodBase<T_SPEED>::IsReadyToUpdate() [with T_SPEED = NeoEsp8266DmaSpeedWs2812x]' discards qualifiers [-fpermissive]

Making IsReadyToUpdate() const solves the issue.
