[FEATURE] Improve performance of KLLSketch and DataType Analyzer

[zeotuan]

Is your feature request related to a problem? Please describe.
Currently, KLLSketch and DataType analyzer is implemented use the UserDefinedAggregateFunction

deequ/src/main/scala/com/amazon/deequ/analyzers/catalyst/StatefulKLLSketch.scala

Line 29 in 3b1a3ec

private [sql] class StatefulKLLSketch(

deequ/src/main/scala/com/amazon/deequ/analyzers/catalyst/StatefulDataType.scala

Line 26 in 3b1a3ec

private[sql] class StatefulDataType extends UserDefinedAggregateFunction {

which is considered deprecated and should be replaced with Aggregator which offer much greater performance which was outlined here apache/spark#25024 (comment)

Describe the solution you'd like
Reimplement StatefulDataType and StatefulKLLSketch using Aggregator

I am happy to help with this implementation.
