binman: Add basic support for debugging performance
One of binman's attributes is that it is extremely fast, at least for a
Python program. Add some simple timing around operations that might take
a while, such as reading an image and compressing it. This should help
to maintain the performance as new features are added.
This is for debugging purposes only.
