Suggested Signed Interest processing requires the client to ensure signed Interests arrive at the server in order, in order to ensure passing verification.
However, NDN network cannot provide in-order guarantee in the general case.
This Feature contains:
isSequencedAfteroption, with default value false
CommandOptions, change the semantics of
timeoutoption to be "maximum duration of command execution since sending signed Interest"
Controller, keep track of in-progress commands
options.isSequencedAfter==true, wait until all prior commands have been either responded or expired, before starting the current command
