Feature Request: show absolute before/after size (not just the diff)

[mhansen]

Hi bloat busters, today I was using bloaty to track down binary size increases.

I got output like this:

    FILE SIZE        VM SIZE
 --------------  --------------
  [NEW] +1016Ki  [NEW]  +360Ki    proto2::internal::InternalMetadataOffset::Build<>()
   +56%  +761Ki   +62%  +293Ki    proto2::RepeatedPtrField<>::RepeatedPtrField()

I wanted to add a column showing the absolute size before. I suppose I can work it out with some maths using something like:

X2 = X1 + 761Ki
X2 = X1 * 1.56
X1 + 761Ki = X1 * 1.56 # set both sides equal
761Ki = X1 * 0.56 # subtract X from both sides
761Ki / 0.56 = X1
X1 = 1358

But it would be great if users didn't have to do this. Thank you!
