Mathieu Duponchelle 805e0f66af ceax08overlay: fix field lookup for s334-1a
As stated in the spec:

> Bit b7 of the LINE value is the field number (0 for field 2;
> 1 for field 1). Bits b6 and b5 are 0. Bits b4-b0 form a 5-bit unsigned
> integer which represents the offset [..]

Here, b7 is the most significant bit, this is what both cccombiner
and ccconverter agree on.

The overlay elements previously looked at the least significant bit,
which led to garbled text when both fields were actually present
in the CC meta.
