feat: parse inline object types

[buehler]

Related to #79

while parsing property of type Object (e.g. { myProperty: { innerPropery: string } }, the type is not fully parsed and returns values like
{\n email: string\n }

Ah yes I've just been battling this. At least the value is still present.

As a result I can simply check for an inline object with type.match(/{.+}/s) and then recursively walk in and use parseSource. (But gee it's a pain that parseSource is async - makes the simple bit of code much more verbose than it should be.)
