Enhance README format and structure as per template

[ahmadiq]

• reformat and restructure according to this template: https://github.com/stakater/README/
• add in missing content. the Readme should clearly define what the project is/does and how it should be run and used.
  • Does this need to fit here, or should it be kept seperate: https://github.com/trade-nexus/documentation/blob/master/Creating%20TradeSharp%20Installer.md
• review and add appropriate badges at the top of the readme
