Studio下使用DAP下载器的问题

先问下大家有在studio上使用DAP成功烧录的吗？
我用的雅特力开发板，自带AT-Link（本质上是DAP）。使用studio烧录的时候报错：

`pyocd.core.exceptions.TargetSupportError: Target type 'at32f403avgt7' not recognized`

```
D:\RT-ThreadStudio>D:/RT-ThreadStudio//repo/Extract/Debugger_Support_Packages/RealThread/PyOCD/0.1.0/pyocd.bat flash --target=AT32F403AVGT7 G:\MCU\AT32\Project\ATF403_nano\Debug\rtthread.bin 
0002050:CRITICAL:__main__:Target type 'at32f403avgt7' not recognized. Use 'pyocd list --targets' to see currently available target types. See <https://github.com/mbedmicro/pyOCD/blob/master/docs/target_support.md> for how to install additional target support.
Traceback (most recent call last):
  File "pyocd\board\board.py", line 61, in __init__
KeyError: 'at32f403avgt7'
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
  File "pyocd\__main__.py", line 362, in run
  File "pyocd\__main__.py", line 516, in do_flash
  File "pyocd\core\helpers.py", line 242, in session_with_chosen_probe
  File "pyocd\core\session.py", line 179, in __init__
  File "pyocd\board\board.py", line 67, in __init__
  File "<string>", line 3, in raise_from
pyocd.core.exceptions.TargetSupportError: Target type 'at32f403avgt7' not recognized. Use 'pyocd list --targets' to see currently available target types.
```
然后我到了studio的安装目录测试`PyOCD`发现两个问题：
1. PyOCD被发布为成了单个的exe程序，python发布的单个exe程序启动很慢，而studio本身集成了python，直接使用脚本体积小速度块这多好呀。如果要发布exe建议改成零散的文件速度也会快很多
2. 测试'pyocd list --targets'命令会报一堆错误，更奇怪的是错误提示里面怎么还有个其他计算机账户的路径
