identify whether or not a file is zipped in remote accessing of files

[imedan]

I've run into an issue with accessing astra files remotely, where I get an error that the file cannot be found:

In [1]: import sdss_access

In [2]: sdss_access.__version__
Out[2]: '3.0.3'

In [3]: import tree

In [4]: tree.__version__
Out[4]: '4.0.5'

In [5]: from sdss_access import Access, RsyncAccess

In [6]: access = RsyncAccess(release='ipl3')

In [7]: access.remote()

In [8]: access.add('mwmAllStar', v_astra='0.5.0')

In [9]: access.set_stream()
[ERROR]: Traceback (most recent call last):

This does not seem to happen when accessing the file at Utah:

from sdss_access.path import Path
p=Path()
p.full('mwmAllStar', v_astra='0.5.0')
'/uufs/chpc.utah.edu/common/home/sdss50/sdsswork/mwm/spectro/astra/0.5.0/summary/mwmAllStar-0.5.0.fits.gz'

p.exists('mwmAllStar', v_astra='0.5.0')
True 

This issue then seems to be a bug where sdss_access is not correctly utilizing the feature to identify whether a file is zipped or not with remote access.
