fix browser minified output file

[juliancwirko]

There is a problem with minified erdjs for the browser. For the demo from here:

https://gist.github.com/juliancwirko/f31aab85d735d7b86162de4c4da33b1f

When I use erdjs.min.js instead of erdjs.js, I will get the error. See attached image.

After using terser instead of tinyify seems to work well, the compression level is a little bit better, and I think terser is a lot faster.

I've tried to run the browser tests. Some of them fail, but the same is on the development branch.
