I tried installing BIDS Helper version 22.214.171.124 with VS 2015 already installed and I don't see any components of BIDS Helper. Is it not supported yet?
Output of Help->About is here:

VS 2015 only supports the SQL 2016 tools. There is no version of v1.7.0 for SQL 2016 as it was released before SQL 2016.
You would have to use the preview release for SQL 2016 to use BIDS Helper in VS 2015.
