best_prefix() returns MiB for Bit rather than Mib

[rohit04saluja]

The best_prefix of a bit unit comes as MegaByte. b -> M

How to REPRODUCE the issue:

>>> import bitmath
>>> b = bitmath.Bit(30950093.15655963)
>>> b
Bit(30950093.15655963)
>>> b.best_prefix()
MiB(3.6895386167239703)
>>>

How REPRODUCIBLE (every time? intermittently? only in certain environments?): Happens every time.

What you EXPECTED to happen: The expectation was the best_prefix() should have returned Mib as the initial unit is in Bit.

>>> b.to_Mib()
Mib(29.516308933791763)
>>>

What ACTUALLY happened: best_prefix() returned MiB

>>> b.best_prefix()
MiB(3.6895386167239703)
>>>
