Middleware type definition misses DecoratorTarget

Current behavior

Hi,
I've updated library inversify-express-utils from 6.3.2 to 6.4.10 and I got this build error

Argument of type 'typeof HttpMyBeautifulMiddleware' is not assignable to parameter of type 'Middleware'.

This happens because Middleware definition changed from (v. 6.3.2)
export type Middleware = (inversifyInterfaces.ServiceIdentifier<any> | express.RequestHandler);
to (v. 6.4.10)
export type Middleware = (string | symbol | RequestHandler

The new definition is too small to allow all ServiceIdentifier available in Inversify as you can use a prototype or a contructor function as decorator target.

Steps to reproduce

1. Create an empty inversify express project
2. Create a class HttpMyBeautifulMiddleware that extends from BaseMiddleware
3. Register class HttpMyBeautifulMiddleware with .toSelf() method
4. Create a controller using HttpMyBeautifulMiddleware as middleware with its type definition.
   For example @controller('/api/welcome', HttpMyBeautifulMiddleware)

Expected behavior

Build must complete successfully

Possible solution

I suggest to add DecoratorTarget to Middleware definition as you can see below
export type Middleware = (string | symbol | RequestHandler | DecoratorTarget<{ handler: RequestHandler }>

This is enough to make build and running complete successfully keeping middleware type checking.
