[NTG-context] setmemstream to use pdfe.new instead of epdf.openMemStream

I am using the "figures.setmemstream" for inline images and it is
broken now with the latest luatex on the changes from
epdf.openMemStream to pdfe.new.

Although it does say "very experimental and likely to change", but can
we update the call from epdf.openMemStream?

Minimal example:

or as in grph-mem.lua:
-- \startluacode
--     figures.setmemstream("whatever",io.loaddata("t:/sources/cow.pdf"))
-- \stopluacode
-- \externalfigure[memstream:///t:/sources/cow.pdf]
-- \externalfigure[memstream:///whatever]

The error message is:
/usr/share/texmf/tex/context/base/mkiv/grph-mem.lua:32: attempt to
index global 'epdf' (a nil value)
stack traceback:
    /usr/share/texmf/tex/context/base/mkiv/grph-mem.lua:32: in
function 'setmemstream'
    [ctxlua]:2: in main chunk

Which points to the line of "local memstream, identifier =
LuaTeX commit 6822 change was "epdf.new (aka memstreams) (HH)"
