Spectrochempy

New features

* add nnl and pnnls solvers to MCRALS

These are the changes in SpectroChemPy-0.6.2.

New features

* `PLSRegression` (Partial Least Squares regression) method added.

* `read` method now handle any url pointing
to a spectrochempy readeable file. An url to a compressed (zip) files are also accepted.

Example:

.. code-block:: ipython

lst = scp.read("https://eigenvector.com/wp-content/uploads/2019/06/corn.mat_.zip")
lst contains 7 NDDatasets,, display the last
lst[-1].plot()

* Automatically download the github repository ``spectrochempy_data`` which contains the files
for the examples and tests. The files are downloaded in the directory scp.preferences.datadir.
When the program is run for the first time, the availability of the files may take several
minutes, depending on the quality of the internet connection.

Bug fixes

New features

* Improved loading time
* Plot2D accept a color argument. In addition to cmap=None,

produces a dashed red stack plot.

Bug fixes

* Masks handling.
* Multicoordinates slicing work correctly.
* Removed some deprecation warnings from numpy library.
