Vernier profiles can't be viewed locally

[gmcgibbon]

The default viewing profile action doesn't work with Vernier profiles:

app_profiler/lib/app_profiler/profile/vernier.rb

Lines 18 to 22 in 7a0f861

	def view(params = {})
	raise NotImplementedError
	end
	end

We should implement this so Vernier can be use out-of-the-box like Stackprof can. We can probably use profile-viewer like we do speedscope.

@gmcgibbon there is actually a PR waiting for you to review #111 we had reviewed it together but i think it fell off the radar. I just rebased it and re-fixed rubocop.

[gmcgibbon]

#111 is merged, which helps, but I'm still going to work on a local version of the middleware and that requires change the profile-viewer. Working on that next.

Thanks @gmcgibbon !
