TypeOperator not supported by ts-interface-builder: keyof SomeInterface

[TomascpMarques]

TL;DR

Be able to use field: keyof SomeInterface as an interfaces field type, without needing to export custom types.

What's the issue?

Using keyof SomeInterface, as an interface field, type__throws out an error__ :
Node TypeOperator not supported by ts-interface-builder: keyof IUser

What happened?

So I was defining a new interface, and in one of the fields I defined the as field: keyof IUser, and when I ran the:
npx ts-interface-builder foo.ts it gave me the previously mentioned error.

What did you try to fix the issue?

After the error message, I used the Type suites, exported the type, rewrote the previous error producing code using the exported type, and it does not work, it builds, but still throws out an error.

What do you want?

Be able to use field: keyof OtherInterface directly, pretty pls

P.S

I'm loving your package, eases my development experience tremendously, loving it <3
