[TypeScript] publish new package name to DefinitelyTyped

[davidroeca]

There is currently a package named @types/jexcel and it is probably worth adding a new version that matches the name here (@types/jspreadsheet-ce). I may get around to this later this week; for now, I'm just using a declaration within the app I'm working on:

declare module "jspreadsheet-ce" {
  // Not sure all declarations here are necessary
  export * as jexcel from "jexcel"
  export * as jspreadsheet from "jexcel"
  export default jexcel
}
