* Moves off of draining between filters. Instead, the sink will pull on the stream, and will drain element-wise. This moves the whole stream to being lazy. * Adds ctrl-c support and connects it into some of the key points where we pull on the stream. If a ctrl-c is detect, we immediately halt pulling on the stream and return to the prompt. * Moves away from having a SourceMap where anchor locations are stored. Now AnchorLocation is kept directly in the Tag. * To make this possible, split tag and span. Span is largely used in the parser and is copyable. Tag is now no longer copyable.
