feat(3p/lisp/mime4cl): cache offset in delimited-input-stream r/3749
By computing the amount the stream position advanced we can save a
syscall on every read which speeds up mime:mime-body-stream by /a lot/,
e.g. extracting a ~3MB attachment drops from over 15s to under ~0.5s.
There's still a lot to be gained and correctness left to be desired
which can be addressed as described in the newly added comment.
