I added 10 handy Typescript helper types

1. At Least One Key
  Ensures that at least one property of an object is required.
2. Deep Partial Type
  Converts all properties of a type, including nested objects, into optional.
3. Deep Read-only Type
  Converts all properties of a type, including nested objects, into readonly.
4. Deep Required Type
  Converts all properties of a type, including nested objects, into required.
5. Keys of Type
  Extracts keys from an object type that match a specified value type.
6. Keys to Optional
  Makes only the specified keys of an object type optional.
7. Nullable Keys
  Extracts keys from an object type that allow null or undefined values.
8. Omit Keys of Type
  Removes keys of a specified type from an object type.
9. Required Keys
  Extracts required keys from an object.
10. Union to Intersection
  Converts a union type into an intersection type.
