Goodman Pipeline V1.2.0 release

• Bugs removed:

  • If there was more than one lamp for a science target the lamp recorded as used
    was one of them only.
  • A percentage symbols was added to the help of --saturation argument, this
    caused a crash when redccd -h or redccd --help was used.

• Numpy is fixed to the version 1.15.2 until further notice.

• Reference lamps now get the extraction window added to the end of the file name.
  This is to avoid overwritting the lamps when they were used for more than one target.

• DCR install script is now more advanced and requires a virtual environment to work on.

• Added SOAR Logo to ReadTheDocs page.

• Changed install instruction with exact steps and commands instead of
  referencing documentation.

• Improved method to detect saturated images. Added a table with the half full
  well for all the readout modes possible and created a method to easily
  retrieve the value. This is a big improvement since in earlier versions the
  saturation limit was set to 65000 ADU regardless the input data and the user
  had to set a different one using the argument --saturation.

• Repurposed the --saturation command line argument, now is used to define
  the percentage of pixels above the saturation level, which for simplicity is
  the value of half full well. A default value of 1 percent was set as default.

• Added record information of target trace into the header and logs.

• Added record of background extraction regions into the header and logs.

• Made all plots full screen and the images using the gray cmap.

• Trace information is printed in the logs and also is recorded in the image's
  header

• Added sigma clipping to target tracing functions
