java.lang.NoSuchMethodError: scala.Predef$.refArrayOps([Ljava/lang/Object;)Lscala/collection/mutable/ArrayOps;

Hi,

I am using Spark 3.0, perhaps this is the cause of the following error:

`val tsRDD = TimeSeriesRDD.fromDF(dataFrame = dffg_ts)(isSorted = true, timeUnit = MILLISECONDS)

java.lang.NoSuchMethodError: scala.Predef$.refArrayOps([Ljava/lang/Object;)Lscala/collection/mutable/ArrayOps;
at com.twosigma.flint.timeseries.TimeSeriesRDD$.canonizeDF(TimeSeriesRDD.scala:331)
at com.twosigma.flint.timeseries.TimeSeriesRDD$.fromDF(TimeSeriesRDD.scala:303)
... 62 elided`

Be great to get it to work. Thanks
