Change firmware requirements.

The most useful reason for memecore to exist is to have it on 3.61, that way you can skip hassle updating to 3.65 and then downgrading to 3.60. Same goes for 3.63/3.67 as it's supported by h-encore. Though it should be mentioned that downgrade is recommended(if not necessary) when installing.

okay, I will fix it and release 1.81 later

3.63 support with h-encore is an undocumented possibility (because kernel nids match), needs to be tested if it still works with h-encore 2.0 (it did with 1.0).

@StepS- already tested, confirmed not working
