[Mini-NDN] [EXT] Timeouts in MiniNDN

[Junxiao Shi]

Hi Andre

You can express multiple Interests one after another, and then wait for
responses.
In ndnping, expressInterest is called at a fixed interval, independent from
whether previous Interests were satisfied.

To retrieve files, or more generally, segmented objects, most libraries
have a helper for that.
In ndn-cxx it's called SegmentFetcher.

See also https://yoursunny.com/t/2021/NDN-face/ , "Face in Libraries"
section, for a deep explanation on how the library Face works.

Yours, Junxiao
