[Task] Build a Results parser that returns the results for a given round

[jd-erreape]

We would like to create Quiniela::Parsers::Results class with a #round method that will provide the ability to return the results for a given round provided as an integer.

The format of the results will be a multidimensional array with 15 elements where each of the elements will be an array with:

[HomeTeam, AwayTeam, HomeResult, AwayResult]

The order of the elements in the array will be the same order they appear on the current Quiniela.

In case we try to provide results for a round that doesn’t exist, we will raise a Quiniela::Parsers::Result::NotFound error
