add nested array parsing support aka ARRAY<ARRAY<...>> #101

Closed odeke-em closed 1 year ago

Not a common nor urgent pattern but let's add nesting of nested arrays. We already have the routine for recursively walking down times. Let's add it just in case someone stored matrices and needed to pull that data into Spark

Nested Array is not supported in the Cloud Spanner. Cleaning the issue.
