Changes proposed in this Pull Request:

With the new get and set methods of brands getting added to Woo i wanted to test with a good amount of testdata.
But saw that the feature wasnt implemented into Smooth Generator (#163).
I went ahead and added that feature like this:

• Implemented a new faker collection from the same provider so we get proper brand names (see here)
• generate brands in case not enough are set
• generate products and assign 1(one) brand to the product

Closes #163 .

How to test the changes in this Pull Request:

1. implement PR
2. generate x products
