Quadmesh flips image upside down

[ahuang11]

import os
import xarray as xr
import holoviews as hv
import geoviews as gv
import holoplot.xarray
hv.extension('bokeh')

os.system(
    'wget '
    'ftp://ftp.cdc.noaa.gov/'
    'Datasets/ncep.reanalysis.dailyavgs/'
    'surface/'
    'air.sig995.2018.nc'
)

obs_ds = xr.open_dataset('air.sig995.2018.nc')
obs_ds.holoplot.quadmesh(x='lon', y='lat', z='air', groupby='time')
obs_ds.holoplot.image(x='lon', y='lat', z='air', groupby='time')

Or maybe I just don't really know what the difference between quadmesh and image is.

This one is quite bizarre, I didn't think it was possible for a quadmesh to be inverted. Will have to look into this before releasing tomorrow.

Found the issue, the fix should be in the HoloViews release tomorrow.
