Nice to have more types in DataFrameSuiteBaseLike.approxEquals

At present the following test involving an Array will fail.

val arr1 = Array("a","b")
val arr2 = Array("a","b")
val r1 = Row(arr1)
val r2 = Row(arr2)

```
assert(DataFrameSuiteBase.approxEquals(r1,r2, 0.0))
```

This is because the comparsion would use arr1 != arr2 , which is true.
The comparison should use !arr1.sameElements(arr2)

Maybe DataFrameSuiteBaseLike.approxEquals should also cater for Array[T], where T is String, Float, Long, Double.

Shing

Start in DataFrameSuiteBaseLike.approxEquals, the entry point named in the issue, and inspect how Row values are compared. Reproduce the Array("a", "b") example, then cover the requested Array element types and verify that equivalent arrays compare equal in the relevant test suite.
