BER encodings were being miscomputed for certain large arcs. The previous method was a bit wacky (in addition to being buggy) and attempted to encode each arc backwards within the BER output buffer. This switches to a new method which splits the upper 7 bits from an arc and encodes that as a byte, continuing until all bytes of the arc have been encoded, which is much more straightforward. The problematic cases which were reported have now been corrected. Fixes #1520
