Raspberry Pi PicoでArducam OV2640を使う

## やってること
Arducam OV2640で写真を撮影し、接続したSDカードに保存する。

## 環境
マイコン：Raspberry Pi Pico
プログラミング言語：MicroPython
カメラ：Arducam OV2640
SDカードモジュール：[AE-MICRO-SD-DIP](https://akizukidenshi.com/catalog/g/g105488/)

## 参考サイト
[stack overflow「Arducam ov2640 camera not taking/returning data on pico」](https://stackoverflow.com/questions/75201606/arducam-ov2640-camera-not-taking-returning-data-on-pico)

#### 注意
・circuit pythonではありません
・他のArducamやSPI Camで使えるかはわかりません
・JPEGでの撮影のみです
・[stack overflow](https://stackoverflow.com/questions/75201606/arducam-ov2640-camera-not-taking-returning-data-on-pico)のページの一番下のコメントに記載されていたプログラムをAI（たしかCopilot）に修正させたのちSDカードに保存するコードを追加しました。
・SDカードではなく、Pico本体に写真を保存するプログラムもあります。必要な方はコメントで教えて下さい。
