Fix handling of nested list responses

${resp}[2] is bad, @{resp}[2] is good.
@{resp}[0][2] does not work, handled using custom keyword.
This should fix MdsalLowlevelPy response handling.

Return tuple contains time first, prefix-id second.
Prefix_id is a string derived from integer member index argument.
