Incorporate @types/stremio-addon-sdk for improved type safety

[sleeyax]

Finally a project using TypeScript! In case you didn't know, there's a @types/stremio-addon-sdk package which provides types for the manifest, catalog, stream etc. You can install it as a dev dependency: npm i -D @types/stremio-addon-sdk.

For example, the following bad any type:

stremify/server/routes/stream/movie/[imdb].ts

Line 10 in bd8887f

const output: any = {

Could be typed with:

 const output: { streams: Stream[] }  = { };

See @types/stremio-addon-sdk/index.d.ts for the full type definitions.
