Extend the "About SunPeek" section in the README

Problem

As mentioned by @t-gross in the JOSS paper review:

The "About SunPeek" section is very short and general. There is no other information given about the capabilities of the software package.

ToDo

  • Extend the README by adding concrete "What SunPeek can be used for?" statements or examples.
  • Add "Who is SunPeek is For" section
  • Explain the two deployment options (WebUI, Python package)
  • Point to the SunPeek FAQ and Power Check FAQ for more information.
