C++ API，调用conn.run( str ) ，str 是多行字符串，当换行符是WINDOWS系统的CRLF时，报如下错误：
C++ API，conn.run( str )
terminate called after throwing an instance of 'dolphindb::IOException'
what(): 172.29.152.56:38848 Server response: 'Syntax Error: [line #1] Can't recognize token ' script: 'getStreamingStat()'
Aborted
换行符改为UNIX系统的LF时，恢复正常。
在VSCode上，选中多行字符串，Ctrl+E，此时，不管换行符是CRLF还是LF，都运行正常。
