upgrade with mir-algorithm 2.0.0

[ShigekiKarita]

@9il Everything works well with mir-algorithm v2.0.1 except for grain.functions.common.maybeExpand unittest (but integrated tests in the other functions are working)

https://github.com/ShigekiKarita/grain/blob/361fc642f281d88e1dbf5be83d8fc5fe0bf05225/source/grain/functions/common.d#L223-L262

do you have any idea?

opEquals was disabled for ndslices of different dimension count. Does unpack help here?

Yes! thank you.
