Android d.ts generator fails to create typings for nested data class

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 8.5
• Cross-platform modules: 8.5.0
• Android Runtime: 8.5.0
• Android d.ts Generator : 3.0.0
• iOS Runtime (if applicable): 8.5.1
• Plugin(s):

Describe the bug
It seems Android d.ts generator has trouble generating types for data classes declared inside functions.
Generator log output:

Android d.ts Generator Version : 3.0.0
ignoring definitions in missing dependency: android.text.TextWatcher
ignoring definitions in missing dependency: android.view.View$OnFocusChangeListener
Generation of definitions took 712ms.
Typings have been generated in the following directory: ./typings

To Reproduce
This is the kotlin function with class declaration: https://github.com/RedMadRobot/input-mask-android/blob/eee78324eb4cdb4faab3248ef646d5750507b598/inputmask/src/main/kotlin/com/redmadrobot/inputmask/MaskedTextChangedListener.kt#L294

These are the typings generated, you will notice a brace is missing on module pickMask:

export module MaskedTextChangedListener {
	export module pickMask {
	export module ValueListener {
		export class MaskAffinity {
			public static class: java.lang.Class<com.redmadrobot.inputmask.MaskedTextChangedListener.pickMask.MaskAffinity>;
			public component1(): com.redmadrobot.inputmask.helper.Mask;
			public getAffinity(): number;
			public component2(): number;
			public copy(param0: com.redmadrobot.inputmask.helper.Mask, param1: number): com.redmadrobot.inputmask.MaskedTextChangedListener.pickMask.MaskAffinity;
			public hashCode(): number;
			public equals(param0: any): boolean;
			public getMask(): com.redmadrobot.inputmask.helper.Mask;
			public toString(): string;
			public constructor(param0: com.redmadrobot.inputmask.helper.Mask, param1: number);
		}
	}
}

Expected behavior
Typings should be generated without problems.

Bắt đầu với khai báo hàm Kotlin được liên kết trong phần tái hiện và so sánh output của nó với các typings được tạo hiển thị trong issue. Theo dõi cách Android d.ts Generator xử lý các data classes lồng nhau và xác minh việc hoàn tất bằng cách tạo lại typings mà không có dấu ngoặc nhọn bị thiếu của module.
