Constructor for creating a <code>MultiRowRangeFilter</code> from multiple rowkey prefixes. As
<code>MultiRowRangeFilter</code> javadoc says (See the solution 1 of the first statement), if
you try to create a filter list that scans row keys corresponding to given prefixes (e.g.,
<code>FilterList</code> composed of multiple <code>PrefixFilter</code>s), this constructor
provides a way to avoid creating an inefficient one.
@param rowKeyPrefixes the array of byte array
