c784820454 introduced a bool option type
as a replacement for the flag type, but didn't actually transition and
remove the flag type because it would have been too much mundane work.
The args struct is reused to attempt opening an URL with
different stream layers, overwriting args->url not only
breaks this but also causes the freed buffer to be used again.
Add support for reading a byte range from a stream via
the `slice://` protocol.
Syntax is `slice://start[-end]@URL` where end is a maximum
(read until end or eof).
Size suffixes support in `m_option` is reused so they can
be used with start/end.
This can be very useful with e.g. large MPEGTS streams with
corruption or time-stamp jumps or other issues in them.
