Various small enhancements and bug fixes
ENH: Radar colormaps

Colormaps which are aimed at Radar moments.

These colormaps were taken from the Deprecated_Matpy project:
https://github.com/pmarshwx/Deprecated_Metpy
https://github.com/pmarshwx/Deprecated_Metpy/blob/master/metpy/vis/ctables.py

Code for converting the color tuples to matplotlib colormaps taken from
the matplotlib project:
http://matplotlib.org/
https://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/cm.py

ENH: Radar colormaps
ENH: Faster reading of sigmet files and support for missing rays

* Sigmet files are read as speeds similar to RSL using the Cython SigmetFile
  object.
* Sigmet files which contain rays which were not collected are returned as
  proper radar object with the missing rays excluded from the data.
ENH: Two addition to sigmet files reading.

* read_sigmet can now accept a file-like object as the filename parameter.
* 1-byte moments can are now converted by SigmetFile objects.
BUG: fixed reading of sigmet files with ray data to the end of the record
ENH: reading of sigmet files with extended headers
