fix(growing): restore proven XDCAM HD422 (MPEG-2 422) rdd9 @1080i59.94

Browse source 
Today's codec churn (h264_nvenc/AVC-Intra/op1a) produced .mxf files Premiere could not open. Subagent diagnosis vs the old working files on the share proved the working format is XDCAM HD422 = mpeg2video 4:2:2 yuv422p, clip type rdd9, wrapped at 1080i59.94 (30000/1001). raw2bmx REJECTS MPEG-2 422 at 60000/1001, so a 1080p59.94 SDI feed must wrap as 1080i59.94. Reverted GROWING_VIDEO_ELEMENTARY_ARGS to mpeg2video, raw2bmx -t rdd9 --mpeg2lg_422p_hl_1080i -f 30000/1001, -f mpeg2video pipe, and rates() 59.94->30000/1001 with 1080 forced interlaced.
