…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

Just discovered a safety bug in this; will update |

Actually, scratch that, it's fine. I was worried that trailing IPv4 addresses meant that the "MAX_LENGTH" was too short (since XXXX:XXXX is shorter than DDD.DDD.DDD.DDD), but we only write out an IPv4 address if most of it is truncated zeroes. |
