Use streaming JSON parser for profile fetch

[pepyakin]

When using samply with large profiles you can sometimes get very large profiles. If an uncompressed profile gets large enough it will get silently truncated and the profile cannot be displayed (see the screenshot attached). As was noted by @mhansen, it's probably the String limit as described here.

In any case, this PR attempts to fix this issue by using a streaming JSON parser instead of trying to swallow the trace awhole.

Hey there @canova . Is there anything I can do to help pushing this in?

I haven't looked in any detail yet, but I tried the deploy preview with a large-but-not-too-large profile and I still see the old path being used: https://deploy-preview-5578--perf-html.netlify.app/public/fkmw9djz29ntsmaznezy93hhft85jy0zjrp5my8/calltree/?globalTrackOrder=0&profileName=FullSp3Firefox-15x-symbolicated&thread=0&v=12

Is this expected? I would like to compare the performance.
