Add values function to ease insertion of multiple columns worth of data

[mihaisoloi]

There are already tests for value which is a special case of values.

This is to handle: #41

Argh seems like 2.12.x doesn't have ListMap.from
https://github.com/kaizen-solutions/virgil/runs/5649226782?check_suite_focus=true#step:6:19

This should work and be just as efficient as what ListMap.from was doing:

val allColumns = column +: rest
val underlying: ListMap[String, ValueInCql] = {
  val acc         = ListMap.newBuilder[String, ValueInCql]
  val withColumns = acc ++= allColumns
  withColumns.result()
}
val columnsToAdd = BindMarkers.from(underlying)
