Get versions of columns only within the specified timestamp range, [minStamp, maxStamp) on a
per CF bases. Note, default maximum versions to return is 1. If your time range spans more than
one version and you want all versions returned, up the number of versions beyond the default.
Column Family time ranges take precedence over the global time range.
@param cf       the column family for which you want to restrict
@param minStamp minimum timestamp value, inclusive
@param maxStamp maximum timestamp value, exclusive
