Include function calls representations as a concrete ColumnRef
Description
Selections within a projection are usually represented as sequences of classes extending `ColumnRef`. `ColumnName` is a common example as its instances are used to select tables columns.

On the other hand, `ColumnRef` is a sealed trait which implies that other projects' classes can't it.
It would be nice to include a `FunctionCallRef` within `ColumnRef.scala`. e.g:
