Change truncation character for floats

Created by: csghone

max-column-width does not work on columns interpreted as float.

eg:

echo "2.132456,156548.54646 2.132456,156548.54646" | xargs -n1 |csvlook --max-column-width 10
| 2.132456 | 156548.... |
| -------- | ---------- |
|   2.132… | 156,548... |

Expected behavior (or Workaround):

echo "2.132456,156548.54646 2.132456,156548.54646" | xargs -n1 |csvlook -I --max-column-width 100
| 2.132456 | 156548.54646 |
| -------- | ------------ |
| 2.132456 | 156548.54646 |
