Reduce the screenshots size (facebook#54800)

Summary:

# Changelog: [Internal]

From my observations, currently every base64 string for encoded screenshot takes on average ~100Kb. This is too much. These changes reduce the size to ~6Kb, at a cost of quality.

We can't accomodate such big strings, because there could be hundreds, if not thousands of frames for a ~10-20s trace.
