MongoDB TSchema implementation

[loopingz]

Describe the bug
With new mongodb library, compilation fails because TSchema is default one, we used <unknown> cast to prevent the compilation failure but we should implement a TSchema for our object

src/mongodb.ts:321:7 - error TS2769: No overload matches this call.
  The last overload gave the following error.
    Type 'string' is not assignable to type 'Condition<ObjectId>'.

321       _id: uid
          ~~~

  ../../node_modules/mongodb/mongodb.d.ts:5858:5
    5858     _id: InferIdType<TSchema>;
             ~~~
    The expected type comes from property '_id' which is declared here on type 'Filter<Document>'
  ../../node_modules/mongodb/mongodb.d.ts:1466:5

    The last overload is declared here.
