Difficult to quickly see largest allocations

[fonsp]

In a table like this one, it is difficult to quickly see which tests had a large number of allocations, you have too read carefully to find GB instead of MB:

Ideas:

• Use colors/bold to highlight the highest values in a column. Or to highlight >1GB values.
• Show everything in integer MB. 1.23GB would show as 1234MB, clearly standing out over 123MB and 12MB.
• Show sizes >1GB with 4 significant digits, <GB with 3 (as we currently do). That way, all >1GB numbers will stand out. But 123MB and 1.23MB will still look very similar.

You can use sortby=:allocations to the printing so big allocations will be at the top. You also see the %tot in the right column which makes it pretty clear, no?

😅 Just realised what the %tot column does, that's what I needed, thanks!
