Wish: add back READ/binary and WRITE/binary

[Oldes]

If there is something what I must change in almost every old Rebol2 script to have it working with Rebol3 and or Red, than it is this change of read and write refinements.

Red does not have /string refinement and instead has /as encoding, which may be also fine to support. I know, that this R3 change was done to have read/write as low level, but I believe that we don't have to be so low and to be limited only with binary.

I think that it is ok to keep the default binary behaviour, but it would be also nice to have a chance to refine the required actions. Especially when read/write may be used for more scheme types than files or http request.

This still seems to me to be a big open area.

I think if I had to pick a side, I would say keep READ and WRITE as byte-oriented, then let LOAD and SAVE bring in higher level decodings.
