The function _extractJsonFromResponse was assuming that anything that's not a zip file must be JSON. However this means that from-url wasn't working with binary profile formats (json-slabs, simpleperf, art trace).

This PR makes it so that fetchProfile no longer calls JSON.parse, but instead the interpretation of the bytes happens entirely within unserializeProfileOfArbitraryFormat.
