commandline paras are too generall

[JamesOlvertone]

When you set --base32 are all hashes are base32. But I dont want that. make it work for only selected hashes and implement another explicit switch that base32 all hashes, eg:

only discinct hashes are bas32'ed:
--md5_b32 --sha1 --sha256_b32 ...
all given hashes are base32
--all_base32 --sha1 ...

The great advantage that rhash can caluclate a large number of hashes is fading away with this issue. you have to read the files again, thats annoying.

[rhash]

As workarround use --printf option with "b" prefix for base64 encoding:

$ rhash --printf '%b{sha1} %{md5} %p\n' empty_file.txt
