Format .d.ts file

[rhysd]

Type definition file is useful not only for TypeScript compiler but also for programmers to know the API. However, current .d.ts file generated by wasm-bindgen is not fully formatted.

This patch improves readability of generated .d.ts file by fixing some formats

• Give each class member 2 spaces indentation
• Remove unnecessary space before function name
• Remove unnecessary blank lines
• Give 2 space indentations to each enum variant

I applied my patched wasm-bindgen to my project. Here is the result.

Before applying this patch:

/* tslint:disable */
export enum Resolution {Low,Middle,High,}
export enum LandKind {Sea,Mountain,Forest,Plain,Town,Top,Highland,DeepSea,Path,}
export class Cell {
free(): void;
kind: number;
altitude: number;

 color_code(): string;

 rgb_color(): number | undefined;

 legend(): string;

}
export class Generator {
free(): void;

static  new(): Generator;

 gen_auto(arg0: number, arg1: number): Board;

 gen(arg0: number, arg1: number, arg2: number): Board;

}
export class Board {
free(): void;

 width(): number;

 height(): number;

 at(arg0: number, arg1: number): Cell;

 as_json(): string;

}

After applying this patch

/* tslint:disable */
export enum LandKind {
  Sea,
  Mountain,
  Forest,
  Plain,
  Town,
  Top,
  Highland,
  DeepSea,
  Path,
}
export enum Resolution {
  Low,
  Middle,
  High,
}
export class Board {
  free(): void;
  width(): number;
  height(): number;
  at(arg0: number, arg1: number): Cell;
  as_json(): string;
}
export class Cell {
  free(): void;
  kind: number;
  altitude: number;
  color_code(): string;
  rgb_color(): number | undefined;
  legend(): string;
}
export class Generator {
  free(): void;
  static new(): Generator;
  gen_auto(arg0: number, arg1: number): Board;
  gen(arg0: number, arg1: number, arg2: number): Board;
}

Looks great to me, thanks! No need to worry about that error
