Proc::Async page doesn't mention stdout/stderr/Supply candidates with :enc + :translate-nl

[timo]

in method new it says:

The :enc specifies the encoding for streams (can still be overridden in individual methods) and defaults to utf8.

but the text for methods stdout, stderr, and Supply don't have anything about that.

The implementation has a proto method for each of these that either takes a :bin (can be False which forwards to the method without :bin) or :$enc and :$translate-nl.

These should be in the docs page for Proc::Async as well.
