BufferedSource.readUtf8Line as Sequence<String>(kt) and Stream<String>(java)

[MukjepScarlet]

We have BufferedReader.lines(): Stream<String> in Java, so I hope that BufferedSource can also integrate similar APIs.

I did an extension for that:

fun BufferedSource.utf8Lines(): Iterator<String> =
    object : AbstractIterator<String>() {
        override fun computeNext() {
            val nextLine = readUtf8Line()
            if (nextLine != null) {
                setNext(nextLine)
            } else {
                close()
                done()
            }
        }
    }

One issue is that IOException is ignored here
