Add a util for converting ota payload to cow image

VAB team can use this tool to understand what real world COW images look
like, and perhaps write unittests

How to use this tool:
1. mm -j cow_converter
2. `unzip your_ota.zip payload.bin`
3. `unzip target_file.zip "IMAGES/*" -d /tmp/target_file
4. `cow_converter payload.bin /tmp/target_file/IMAGES`
5. inspect generated cow images `ls -l /tmp/target_file/IMAGES/*.cow`

Test: cow_converter payload.bin /tmp/target_file/IMAGES
