------ Vendored from the 'ip' package at 7cbe515d6, with the following trivial
------ changes:
------   - a few derived instances removed from data types
------
------ If you need to add functionality, please do so in a different module (e.g. *.Extended)
------ 
------ Possible paths back to upstream again might be:
------   - requesting a 'ip-types' package with lower dependency footprint

-- | Normalize an 'IPv6Range'. The first result of this is that the
--   'IPv6' inside the 'IPv6Range' is changed so that the insignificant
--   bits are zeroed out. For example:
--
--   >>> addr1 = IPv6.ipv6 0x0192 0x0168 0x0001 0x0019 0x0000 0x0000 0x0000 0x0000
--   >>> addr2 = IPv6.ipv6 0x0192 0x0168 0x0001 0x0163 0x0000 0x0000 0x0000 0x0000
--   >>> IPv6.printRange $ IPv6.normalize $ IPv6.IPv6Range addr1 24
--   192:100::/24
--   >>> IPv6.printRange $ IPv6.normalize $ IPv6.IPv6Range addr2 28
--   192:160::/28
--
--   The second effect of this is that the mask length is lowered to be 128
--   or smaller. Working with 'IPv6Range's that have not been normalized does
--   not cause any issues for this library, although other applications may
--   reject such ranges (especially those with a mask length above 128).
--
--   Note that 'normalize is idempotent, that is:
--
--   prop> IPv6.normalize r == (IPv6.normalize . IPv6.normalize) r
