Huge bundle size of everyone who use this library

[amerllica]

By destructuring import of the Close icon of Material-UI in the supplier.js file, I faced a huge bundle of my project. something about 5mg 😮

For a test, I omit all of my libraries and based on Tree Shaking docs of Webpack I implement the tools and tricks in my project but bundle has no change until I fount the issue and 1 percent I don't think it is material-snackbar-supplier causes to this damn bundle.

Based on this material-ui doc the importing of the Close icon should change to:

import CloseIcon from '@material-ui/icons/Close';

So as fast as I can I send a PR, and please assign the bug tag to this issue and review and merge my PR and please as fast as you can release a new version.

Thanks a lot bro.

I'm wondering why you even change that before.
It's my bad, I should have told you before.
In addition, there is a related optimization article in material docs which is well-eplained too
