Request: Number of columns prop for Row

[apaatsio]

In Bootstrap you can set the number of columns in a row like this:

<div class="container">
  <div class="row row-cols-2">
    <div class="col">Column</div>
    <div class="col">Column</div>
    <div class="col">Column</div>
    <div class="col">Column</div>
  </div>
</div>

I would like to see that supported by styled-bootstrap-grid. The example above would preferably translate to something like:

<Container>
  <Row cols={2}>
    <Col>Column</Col>
    <Col>Column</Col>
    <Col>Column</Col>
    <Col>Column</Col>
  </Row>
</Container>
