Update to network-uri-2.6.4.1

network-uri-2.6.4.1 (2021-02-07)
* Fix: Restore "Safe" designation which was accidentally removed.

network-uri-2.6.4.0 (2021-02-07)
* Add compatibility with GHC 9.0.1.

network-uri-2.6.3.0 (2020-02-18)
* Add official support for SafeHaskell NOTE: This is the first version
  whose SafeHaskell properties have become an intentional part of the
  API contract; previous versions were merely accidentally
  safe-inferred (or not depending on various factors; in other words,
  this was a fragile property).
* Derive Lift instances using DeriveLift extension, when available.

network-uri-2.6.2.0 (2020-01-30)
* Mark the modules as Safe for SafeHaskell.

network-uri-2.6.2.0 (2020-01-30)
* Merge network-uri-static (Network.URI.Static) into this package,
  which offers a way to parse URI strings at compile time.
* Add Lenses for the URI types
* Add Generic instances for the URI type
* Add Lift instances for the URI type
* Optimize isReserved and related character-class functions.
* Start to add some benchmarks for performance analysis
* Fix a bug: Correctly parse IPv6 addresses in URIs.
* Add rectify which normalizes a URI if it is missing certain
  separator characters required by the module. Some users found adding
  those characters inconvenient when building a URI from parts.
* Add nullURIAuth and uriAuthToString, paralleling nullURI and
  uriToString.
