Use valid IR calibration data #8292
Previously, IR calibration data with an invalid checksum was used, because the calibration produced a strange offset. I've replaced it with calibration data that encodes the same values as the data Nintendo falls back to when the checksum is bad.
I've also updated the documentation on wiibrew, though I'm not completely happy with the naming and I'm still not 100% sure what these values mean — but I know enough to at least replace it with the defaults.
It's worth noting that dolphin doesn't use the same value for acceleration as Nintendo defaults to — but it's probably not worth changing that as that would cause issues with TAS and such. Since IR already behaved as if it were the default, it's fine to change this one.
