Specification: Aleph message format for output generated by a VM

[hoh]

This issue discusses the specification of the Aleph messages that are generated by nodes after running code in virtual machines.

The example below contains two kinds of outputs: output is a list of every output produced sent by the function, and export refers to a file stored in Aleph that contains an archive with files created by the function in a specified directory.

The scope contains the call parameters in the format expected by the ASGI interface.
