Object[] map(Reader reader)
Maps file contents to parameters. In your implementation read the data
 from the reader. The reader is closed in the framework, so just read it
 :)
 
 While reading transform the data into Object[][], where external
 dimension are different parameter sets, and internal dimension is the set
 of params per single test call
 
 You can optionally return Object[] with Strings inside, but each String
 must be a string in the same format as what you would normally pass to
 @Parameters({})
