Description
struct.unpack/unpack_from accepts bytes, bytearray memoryview and other buffet-like objects but not mmap.
For reference, the re module accepts all of them and also mmap.
The memoryview object does not accept mmap, either.

Research direction
Start by reproducing the struct.unpack and unpack_from behavior with mmap, then compare it with bytes, bytearray, memoryview, and the re module as described in the issue. Done means the struct APIs accept mmap consistently with the other buffer-like objects; the issue names no source files or tests to run.
