Erin Le 00f927a4e2 mem, python: refactor error message formatting
This commit refactors the error message added to convert.py.
A mapping between the base 10 and base 2 suffix magnitudes
(e.g. k: ki, M: Mi, etc.) and a new function that extracts the
magnitude and numerical value have been added. Also, a warning
message has been added to the toMemoryBandwidth function in
addition to the one in toMemorySize.
