…lacrum Various minor improvements to Ipv6Addr::Display Cleaned up `Ipv6Addr::Display`, especially with an eye towards simplifying and reducing duplicated logic. Also added a fast-path optimization, similar to rust-lang#72399 and rust-lang#72398. - Defer to `Ipv4Addr::fmt` when printing an Ipv4 address - Fast path: write directly to `f` without an intermediary buffer when there are no alignment options - Simplify finding the inner zeroes-span
