Fix hanging erasure writes ()
However, this slice is also used for closing the writers, so close is never called on these.

Furthermore when an error is returned from a write it is now reported to the reader.

bonus: remove unused heal param from `newBitrotWriter`.

* Remove copy, now that we don't mutate.
