Enhance tsEnumNames about json-schema-to-typescript

Another thing - would it be possible to refer to an existing TS enum member? For instance, if I have an enum defined:

MyEnum:
  type: string
  enum: [one, two, three]
  tsEnumValues: [One, Two, Three]

that produces

export const enum MyEnum {
  One = 'one',
  Two = 'two',
  Three = 'three',
}

Now, in another place, I'd like to define that a definition has a certain constant as a property. This is possible using something like:

property:
  type: string
  enum: [two]

and of course that produces 'two' in the output. However, it'd be great to have it output MyEnum.Two. Of course it's possible to write $ref: $/definitions/MyEnum, but that will just compile to MyEnum rather than a specific value.

@vaskevich I'm not sure JSON-Schema supports that. If you can point to where in the spec it does support it, we can add support in JSTT as well.

Well, I found my own thread here again. I was able to work around this by making use of tsType to override the type to be MyEnum.Two, for instance.
