Improve load speed for python payload script
When using update_payload module to read a full OTA, it will attempt to
load the entire payload into memory first, which is slow. Use mmap
instead, as parsing manifest doesn't require the entire payload to be in
memory, only the first couple of MB.
In case of opening a zipfile, use zfp.open(), which returns a streaming
interface.
Test: import update_payload, load an OTA
