Alright, use term_to_binary() for opaque/sexp-style encoding, only 15x slower.

timing_pb_encoding_test_... speed factor=35.95 [2.730 s] ok
...
So, the PB style encoding of the Mpb_LL_WriteProjectionReq message
is about 35-36 times slower than using Erlang's term_to_binary()
and binary_to_term(). {sigh}

All projection store protocol operations are now using Protocol Buffers!
...
So, there's some cheating going on, because some of the parts of
the #projection_v1{} and #p_srvr{} records aren't fully specified.
Those parts are being specified as "opaque" in the field names, e.g.
optional bytes opaque_flap = 10;
optional bytes opaque_inner = 11;
required bytes opaque_dbg = 12;
required bytes opaque_dbg2 = 13;
The serialization that's being used is erlang term sexprs. That isn't
portable. So if/when we really need to deal with a non-Erlang
language, we'll have to straighten this out further.
