v0.6.1

[stefraynaud]

New features

• Add a warning to xoa.open_data_sample that is emitted when the request edfile
  is not an internal data sample [Add a warning to open_data_sample #47].
• Add the xoa.plot.add_shadow, xoa.plot.add_glow and
  xoa.plot.add_lightshading function to add path effects to plots [Add path effects #44].
• Add the xoa.plot.plot_ts function to make T-S diagrams [Add plot_ts #43].
• Add the xoa.filter.demerliac function to apply a Dermerliac filter
  to time serie [Demerliac #41].
• Add support for fine tuning masking in xoa.filter.convolve through the na_thres
  parameter [Demerliac #41].
• Add the xoa.geo.cdist and xoa.geo.pdist functions to compute
  haversine distances respectively between two dataset and with a dataset [Krig #40].
• Add the xoa.coords.geo_stack function to stack longitudes and latitudes
  into another dimension, in a dataset or data array [Krig #40].
• Add the xoa.filter.decimate function to crudely undersample a geographic
  dataset or data array with a radius of proximity [Krig #40].
• Add the xoa.geo.get_distances to compute the Haversine distances between
  locations inside a single dataset or between txo datasets [Krig #40].
• Add the xoa.krig.empirical_variogram function to estimate variogram parameters.
• Add the xoa.krig.VariogramModel to manage a variogram model [Krig #40].
• Add the xoa.krig.Kriger and xoa.krig.krig to perform kriging [Krig #40].
• Add the exclude option to data var and coordinate specifications of
  xoa.cf.CFSpecs instances [Add exclude #38].

Breaking changes

• A single Nan now contaminates the data over the kernel emprise in xoa.filter.convolve
  since na_thres is set to zero by default [Krig #40].
• xoa now requires the gsw package.

Bug fixes

• Fix xoa.regrid.regrid1d so that it works now with time coordinates [Add support for time coordinates to regrid1d #48].
• Fix xoa.regrid.grid2loc so that it works with scalar output coordinates.
• Fix xoa.regrid.regrid1d to prevent conflict in the presence of MultiIndexes.
• Fix search for coordinates that are hidden due to xarray.DataArray.stack.

Documentation

• Add the "Compare Mercator to ARGO" example.
