[chore] Remove duplicate prefixes from sanitizer (#1195)
In the previous changes that expanded the IPv4 and IPv6 deny lists based
on the IANA registries we inadvertently added a number of duplicates.
This is unnecessary as they're already caught by larger prefixes and
means there's less entries to scan.

This change removes all prefixes that are subnets of other prefixes.

Additional IP range validations (#1152)
* [bugfix] Ensure requests happen over TCP

It's possible for the network to be udp4 or udp6. This is rather
unlikely to occur, but since we're given the network anyway as part of
the Sanitize function getting called we might as well check for it.

* [chore] Align reserved v6 blocks to IANA registry

* [chore] Add test for ValidateIP

The net and netip packages diverge in that net.ParseIP will consider an
IPv4-mapped address to be an IPv4 address and as such it would get
caught by the IPv4Reserved list. However, netip considers it an IPv6
address, so we need to ensure the mapped range is in IPv6Reserved.

* [chore] Align reserved v4 blocks to IANA registry

This includes a number of tests for /32's explicitly called out in the
registry to ensure we always consider those invalid.

[bugfix]: Fix IPv6 validation (#1150)
* [bugfix]: Fix IPv6 validation

The current code considers ff00::/8 valid, but contrary to the comment
that's not the global unicast range. ff-prefixes in IPv6 denote
multicast.

This adapts the code to take the same approach as IPv4, explicitly
blacklisting reserved internal/private ranges.

* [chore] Add missing 4 in IPv4Reserved doc comment
