Added simplesignal and prando to notNeededPackages.json

As per https://www.typescriptlang.org/docs/handbook/declaration-files/publishing.html instructions under "Publicize your declaration file", this adds references to two of my projects to the list of NPM packages that do not need declaration types. The packages themselves already ship with their own `.d.ts` file, and their `types` declared within `packages.json`.
