v0.4.3

• minify: Bytes no longer panics on CSS with a data: URI, which made edge.NewStatic with edge.Minify(minify.Bytes) crash at start. It handed tdewolff's CSS minifier no minify.M, which that minifier needs for a data URI; a data URI now comes out in its shorter encoding.
• edge: Static hands Minify's function a copy of each file. tdewolff's (*minify.M).Bytes renames JavaScript in the array it is given, so a script it saved less than a twentieth of went out as written but scrambled, and did not parse.
• writer: tx.Publish(v) hands a value to in-process listeners once the command commits, and w.Subscribe[T](ctx, n) returns a channel of the values of type T, in commit order. It is best effort: a full queue drops the value for its subscriber alone (Stats.Dropped), a crash between commit and delivery loses it, and nothing is replayed, so a listener that must not miss a value reconciles from the data. Stats.Subscribers counts the subscriptions open.
• prom: writer_published_total, writer_publish_dropped_total and writer_subscribers, and a Published values panel in the dashboard's writer row.
