Add fileSize option

In my case, the library I'm using this plugin on gets tree-shaken, so the displayed filesizes don't match.

I would like an option to remove them completely both from the visualization and from the tooltip, since they may be confusing. Ideally only percentages would be displayed.

The option would be something like:

fileSize (boolean, default true) - Collect file size from source code and display it in the chart.

I just published 5.4.0 where i changed UI of treemap a bit. I added notice to tooltip about what is a size and remove size from text labels of nodes.

Thanks!

However I see in the new version that the names increase in font-size to fill all the available space.

This may often be confusing, since shorter names will appear bigger, even if the treemap block is smaller.

It also confusingly creates a Word Cloud visualization effect with the names, which influences the perception of the sizes.
Could you do an option to disable this?

Yep that seems true. My main idea was to reduce sizes to make sure it tries to fit the box instead of being cut on edge.

I do not want to make and support tons of options, my preference is to have reasonable opinionated defaults.

Updated to 5.4.1 it will center labels, but without font grow.
