Make this project compatible with expressjs outside of nestjs

Great point - might just build 2 packages from this repo. You are welcome to restructure the code 2 support both versions. I will take care of the release process.

Even in NestJS I've run into a use case for this. It requires a pretty nasty workaround at the moment to apply the inner function of the Paginate decorator:

// To assemble the PaginateQuery, we fish out `nestjs-paginate`'s paginate query
// factory from the NestJS parameter decorator

// First, we decorate our dec dummy with the Paginate decorator
const dec = class {};
Paginate()(dec, 'fishy fishy', 0);
// And we declare the types of what we're going to fish out
return Object.values<{
  factory: (_data: unknown, ctx: ExecutionContext) => PaginateQuery;
}>(
  // Then we fish out the route args metadata factory for what we just decorated.
  Reflect.getMetadata(
    ROUTE_ARGS_METADATA,
    dec.constructor,
    'fishy fishy',
  ),
  // Then we use the fished out factory to produce the PaginateQuery from the
  // spoofed request context
)[0].factory(null, reqCtx);

It'd be nicer if we split out a getPaginateQuery(req) function.

PS: I must have amnesia, I had appearantly already opened an issue here: #825
