aggregate (optimise a list of route prefixes)

Takes a list of prefixes in conventional format on stdin, and
performs two optimisations to attempt to reduce the length of the
prefix list. The first optimisation is to remove any supplied
prefixes which are superfluous because they are already included in
another supplied prefix. For example, 203.97.2.0/24 would be removed
if 203.97.0.0/17 was also supplied. The second optimisation
identifies adjacent prefixes that can be combined under a single,
shorter-length prefix. For example, 203.97.2.0/24 and 203.97.3.0/24
can be combined into the single prefix 203.97.2.0/23.
