[issue29178] Adding bytes.frombuffer(byteslike) constructor

You're right!  How difficult working with memoryview!

Maybe, memoryview.to_bytes() is better place to add such options.

memoryview(x) can accept multi dimensional arrays, and itemsize can be >=1.
It's too complex when working with byte sequence.
