install image-size in dependencies

[archmoj]

The size-image module should have been moved from dev-dependencies to dependencies in #5075.

This caused the streambed tests to fail:

Hi!

I did not find the time to read the entire the discussion, but IMHO image-size should be in dev dependencies list because, for example, image-size uses the fs module which is not available in the browsers (in my case through webpack). Maybe it is just my specific case but any help is appreciated.

What can I do if, through plotly.js, I get this error:?

Thank you!

@silviubogan unfortunately we cannot move image-size to dev-dependencies while it is required in traces/image:

plotly.js/src/traces/image/helpers.js

Line 11 in 0d79ea9

var sizeOf = require('image-size');

BTW please feel free to open a new issue concerning your problem or alternatively submit a PR to replace image-size with another module that could return the size of an image of png, jpg, bmp and gif formats.
