The Seq() class doesn't handle ArrayType arguments properly

[kmarwah]

The seq module should write ArrayType objects (especially bytearrays– i.e. ArrayType objects consisting of U8 elements) to the seq .txt files in a way which allows them to be read in properly when the .txt file is parsed by ait-seq-send

Hmmmm. Commanding shouldn't support ArrayTypes at all by design. It does as a result of poor type checking on the Argument handler and the details of data type handling. See the Argument documentation for reference to the "valid" types.

We can reconsider that but it should happen prior to any changes here.
