feat: support enable/disable hyper link by forceHyperLink option

[li-yechao]

I need to diable hyper link but I can not use env FORCE_HYPERLINK=0, so I added an option forceHyperLink for marked-terminal

var defaultOptions = {
  // Boolean, force enable or disable hyper link, default is `undefined`
  // If undefined, it will dynamically determine whether the current environment supports hyperlink
  forceHyperLink: undefined
};
