Add bloaty_treemap.py, for visualizing bloaty data
Add bloaty_treemap.py, for visualizing bloaty data

There is so much more that could be done here (some ideas in TODO
comments), but this greatly streamlines the process for average
developers to navigate the code-size of skia executables.

Currently, I'm using a locally built copy of bloaty, but we should see
about using DEPS or adding a fetch-able package to eliminate even more
friction.
