Dependency on non-licensed library round10

Created by: iamprem

I see addition of round10 library as a dependency in this commit: https://github.com/Dash-Industry-Forum/dash.js/commit/d03e8710c8187b32ec80156f36d353ac9a7d60c5#diff-b9cfc7f2cdf78a7f4b91a753d10865a2

I think it is unnecessary to take dependency on a library that doesn't have any license details in its git repo: https://github.com/jhohlfeld/round10
