SpanExtensionsRead Method

Advances the specified rest parameter consuming up to maxLength characters and returns the consumed part. If rest started with a new line before the call, then an empty span is returned. If the whole ReadOnlySpan<char> has been processed, then rest will be ReadOnlySpan<char>.Empty after returning.
