positioner matched to multiple spots

[sbailey]

Using same example as #19:

basedir=/project/projectdirs/desi/spectro/data/20200107/00038674
desi_fvc_proc \
  --infile $basedir/fvc-00038674.fits.fz \
  --expected $basedir/coordinates-00038674.fits \
  --outfile spots-00038674.csv

there are several positioners that are matched to more than one spot, sometimes very far away, e.g.:

from astropy.table import Table
from collections import Counter
x = Table.read('spots-00038674.csv')
for (petal, loc, pinhole), n in Counter(zip(x['PETAL_LOC'], x['DEVICE_LOC'], x['PINHOLE_ID'])).items(): 
    if n>1: 
        print(petal, loc, pinhole, n) 

0 533 0 4
0 509 0 2
0 409 0 2
0 224 0 2
0 205 0 2
0 157 0 2
8 350 0 2
8 248 0 2
7 24 0 2
6 159 0 2
3 494 0 2
7 377 0 2
4 134 0 2
7 443 0 2
7 397 0 2
6 437 0 2

The first case (PETAL_LOC=0 DEVICE_LOC=533) is the fiducial reported in #19, but the others are positioners, e.g.

x['XPIX', 'YPIX', 'DEVICE_LOC', 'PINHOLE_ID'][x['LOCATION'] == 509] 

<Table length=2>
       XPIX               YPIX       DEVICE_LOC PINHOLE_ID
     float64            float64        int64      int64   
------------------ ----------------- ---------- ----------
