Mixly-添加ESP32CAM支持

Mixly 中默认的 `Arduino ESP32` 编译环境是不支持 `ESP32CAM` 的
内存空间过小，Flash 4MB，partitions 也是默认

综上所述，我们自己添加一个开发板编译方式
### 修改 boards.txt(编译配置)
`...\arduino\portable\packages\esp32\hardware\esp32\1.0.6\boards.txt`
```
# 在 boards.txt 文件中追加以下内容

### 添加 esp32cam/pins_arduino.h(引脚定义)
在 `...\arduino\portable\packages\esp32\hardware\esp32\1.0.6\variants` 下，把 `esp32` 文件夹复制一份并命名为 `esp32cam`
![](/media/202304/2023-04-10_112108_0966810.6707572636453477.png)

### 设定 ESP32CAM 模块栏共用 ESP32
`...\blockly\arduino.js`
```js
# 复制 arduino_esp32 的粘贴并修改两处名称为 arduino_esp32cam，其它保持默认即可
