0.15.1

Snapshot that works with zig 0.15.1

Minimal set of changes needed to get this working with 0.15.1 and http.zig

Uses no buffering in the intermediate writers

Will do a big refactor next to make the whole lib conform to the official Datastar ADR, and at that point will stretch this new Io.Writer framework so that the user can specify intermediate buffering if they want

Note that the current drain function will need updating to handle this, as it's supposed to suck bytes from the buffer before consuming the data passed. This will take a bit of fiddling and tuning yet
