Velox support, new licensing and more!

Ncempy is now at version 1.4.0. Here are the major changes:

• Added support for Velox EMD files. We currently only support images (2D) and image series (3D). Check out ncempy.io.emdVelox
• Change to MIT licensing for the io package to permit ncempy.io to be used in more packages. We are trying to support the entire community to improve the ease of use of your own data.

Minor updates:

• Fixed a bug in ncempy.io.ser.serReader where only the first image was loaded and copied many times for time series data
• Updated documentation to use numpy docstrings. The entire package is not there yet, but that will be finished soon.
• Many more changes can be seen in the commit logs.

Please send any feedback, requests and bugs through the Github issues tracker. We will fix them asap.
