Uint8Array is more flexible because it can refer to a subrange within a bigger ArrayBuffer.
This is a more natural fit and avoids the copy in symbolicator-cli.
This logic can be useful independently of redux actions, for CLI scripts which want to support profiler URLs.

Sometimes I've wanted to inspect profiles from the command line, without loading them in the web UI.
Here's an experiment I've been working on, which creates a
pqtool ("profile query"). To test, clone this branch and runyarn build-profile-query-cli- this creates a./dist/pq.jsartifact. Then somehow make it accessible via your path, for example by putting a shell script with the contentsnode ~/code/profiler/dist/pq.js $@into abindirectory in your path.pq load 'https://share.firefox.dev/hash'orpq load profile.json.gzstart a session.Only tested on macOS so far. It uses unix domain sockets so it probably doesn't work on Windows atm.
