拡張子を変更して画像を保存 Extension

使用方法
・タブで画像を開いた状態で拡張機能のアイコンをクリックし、お好みの画像のフォーマットをクリックするとダウンロードされます。
・ページの画像の上で右クリックをすることで拡張子(画像のフォーマット)を変換してダウンロードするメニューが表示されるので、お好みの拡張子をクリックするとダウンロードされます。

以下のフォーマットとして画像を変換し、ダウンロードすることが可能です。
・PNG
・JPEG
・WebP

※SVGを上記拡張子に変換してダウンロードすることはできません。(今後に期待)

変換が必要ない(JPEGをJPEGとしてダウンロード等)場合、変換せずに直接ダウンロードするため、画像の劣化は発生しないと思います。

・アイコン変更
・名前を付けて保存する機能の追加
・その他リファクタリング

ver 1
・PNG, JPEG, WebPへの変換、ダウンロードに対応
