Is it known problem? Are there any way to debug and make it works?

I found at least one thing that maybe a bug (https://github.com/ch32-rs/wchisp/blob/c7a7434f7adfd0dde9933bdb97a252c8f50c77c5/src/protocol.rs#L209C1-L216C14)

            Command::WriteConfig { bit_mask, data } => {
                let mut buf = vec![0u8; 1 + 2 + 2 + data.len()];
                buf[0] = commands::WRITE_CONFIG;
                buf.pwrite_with(1 + data.len() as u16, 1, scroll::LE)?;  // <---- here len seems should be 2 + data.len()
                buf[3] = bit_mask;
                buf[5..].copy_from_slice(&data);
                Ok(buf)
            }

Finally found that changing reset to default 0x4FFF0F4D make deal

    # reset: 0x4FFF0F4D
    # CFG_DEBUG_EN=1、CFG_RESET_EN=0、CFG_ROM_READ=1
    # enable 2-wire debug
    reset: 0x4FFF0FD5

Good PR will be implementation for config set in order to setup custom value and keep reset same as WCHISPUtil default.
