aggressive: []byte from netip.Addr.AsSlice should not be printed with %s

[ainar-g]

(This could technically be a part of a larger feature regarding printability of []byte, but I've decided to only file the one I've met in the wild. Feel free to retitle/expand.)

Initial code:

ip := net.ParseIP(s)
process(ip)
processAsSlice(ip)
fmt.Printf("address: %s\n", ip)

With processAsSlice accepting []byte.

After some time, process starts to accept netip.Addr instead of net.IP. So, a refactoring is made:

addr := netip.MustParseAddr(s)
ip := addr.AsSlice()
process(addr)
processAsSlice(ip)
fmt.Printf("address: %s\n", ip)

This looks okay, except that netip.Addr.AsSlice returns []byte, not net.IP. So, fmt.Printf doesn't print, say, 1.2.3.4, but rather the bytes with the values \x01\x02\x03\x04.

There is technically a possibility that someone actually wants to print those bytes, so I'm proposing this one for the aggressive mode, but I also feel like 99 % of this sort of code is a bug.
