In nverno/prisms: Package the segment prism data

For most years (1989, 1998-99) prism estimates were collected at three locations on sampled segments: start, middle, end. In 1988, only the start and end locations were sampled. Also, in 1988-1989 only data on PIRU were collected, whereas in 1998-1999 prism data was collected for all species.

Separate prism values were collected for LIVE and DEAD trees, and for SNAG trees as well in some years (all except 1988).

The prism collection points are labeled CTP[1-3], 2 being the middle of the segment. The 'CTP' column is the weighted average of the three, 2*middle + start + end.

Notes:

1988: Only PIRU was counted (LIVE and DEAD) at the beginning and end of each segment.
1989: Only PIRU - start, middle, end prism samples
1998-1999: All species - start, middle, end prism samples
