Improve in-editor display

[pfitzseb]

Currently, timings/number of ticks are displayed as code lenses:

Imho, this is slightly annoying because a) it moves your code around and b) it's hard to get a quick overview over which line in your code is expensive to execute.
I'd like to propose an alternative display mode that instead changes the line background color up to a width proportional to the amount of time spent on that line relative to the current frame's total time (Juno has that feature):

Ignore the drastically different results for now, I think our Julia -> .cpuprofile translation has a bug somewhere.

This is possible with the current decoration API, but might require padding the end of the line with spaces.

+infinity for this one!!!

Just a small bump for this, I tried to use our profiler the other day, and having this would be very welcome :)

What's the status of this? As far as I can tell, timings aren't shown at all now, just ticks. And it is now no longer possible to view the self time/ticks of a function as opposed to the total time/ticks. Both pieces of data are important to report, in my opinion: consider a line like

g = f.(A).^2

The total time tells us how much time is spent executing f, whereas the self time tells us how much time is spent allocating the result vector and taking the power.

Possibly a separate issue, but the table view is also gone, which removes the other place in which self vs. total times could have been read.

Edit: As @pfitzseb rightly points out, I posted this in the wrong place. I was referring to the behavior of vscode for Julia (which stopped using this tool), not this visualization tool in general.

Note that the Julia extension is no longer using this package for visualization.
