[sipayRT]

trafficstars

The purpose of this PR is:

To decrease deps size from 8.7Mb to ~200Kb

This is what had to change:

In the fetch-blob package version 3.x, there was a dependency on the web-streams-polyfill package, which had a large size. In version fetch-blob@4, this dependency was dropped

This is what like reviewers to know:

The API in the major version of the fetch-blob package remains unchanged
