[yt-dev] Issue #883: 1D Enzo data is incorrectly parsed (yt_analysis/yt)

New issue 883: 1D Enzo data is incorrectly parsed
https://bitbucket.org/yt_analysis/yt/issue/883/1d-enzo-data-is-incorrectly-parsed

Nathan Goldbaum:

For some reason the on-disk hydrodynamic fields are interpreted as particle fields and given field type 'io' instead of 'enzo'.  This uses the attached 1D sod shock dataset.


```
#!python

import yt
import pprint

ds = yt.load('DD0001/data0001')

pprint.pprint(ds.field_list)
```

This outputs:


```
#!

[('io', 'y-velocity'),
 ('io', 'x-velocity'),
 ('io', 'Density'),
 ('io', 'z-velocity'),
 ('io', 'TotalEnergy'),
 ('all', 'z-velocity'),
 ('all', 'y-velocity'),
 ('all', 'x-velocity'),
 ('all', 'TotalEnergy'),
 ('all', 'Density')]

```
