Addition to the README file

Hi.
Thanks for another great piece of software for the Wii U.

I never used an Amiibo and I don't own any Amiibos.

I tried this for the first time on BOTW, to get Epona, with the gamepad off (to save battery), I was using the pro controller.
During the game, I accessed the re_nfpii settings, enabled re_nfpii emulation, and waited, and nothing happened.
I then thought "maybe the gamepad needs to be turned on", I turned on the gamepad and Epona appeared immediately.

I just wanted to tell you to write somewhere on the README that the gamepad needs to be ON for the plugin to work, which makes sense because real amiibos are scanned on the gamepad, but ignorant people like me might not know that.

Just an update: I noticed that I only need to turn on the gamepad for the first scan, after the first scan all the others will work even if the gamepad is off. I tested only in BOTW.

Another update:
on BOTW, sometimes I have to turn on the gamepad the first time I want to scan an amiibo (the next times the gamepad can be off), and another times I don't ever need to turn on the gamepad;
on Shovel Knight, I need to have the gamepad on everytime I try to scan an amiibo.
So, this looks to be game related.
