Capturing array events

[Braqzen]

It is unclear how an array may be logged and captured in the indexer.

When building there is a compilation error for an ABI implementation mismatch (although this may have been my own mistake after fatigue, nevertheless my opening sentence stands). This occurred when the arrays have been defined in the same way in Sway and in the indexer.

In part the following issue may be related. Ref #1475

I have a feeling this might be related to #1383 - but someone will have to double check
