Anything that is not `-` or `date` should be use as type for interfaces

[shackra]

As stated.

Something like:

type Custom struct {
    MyValue `ts:"MyCustomType"`
}

Should become:

interface Custom {
    my_value: MyCustomType
}

For importing the types, I use a script with something like echo "import {Type} from '@types'" > src/types/golang.ts before running struct2ts, if someone is wondering.
