quick-xml 0.39.4 on Rust Cargo

#957: Fix slice-index panic when reading malformed DTD whose unknown markup is split across BufReader chunks. As with #950, the returned Event::DocType may contain the malformed DTD; this fix only ensures that the parser does not panic.
#960: Fix sibling slice-index panic when a single chunk delivers < followed by 9+ bytes of unknown markup inside a DTD internal subset. Same disposition as #957 / #950: parser must not panic; DTD validity reporting is a future improvement.
