I`m working on this with my enh/cython branch

involve connection, cursor, result, schemeless_insert, statement, consumer
more pythonic, faster, using cython
code work was almost done, hopefully som day, it might be merged into main branch
but now, more test is needed

连接器只提供接口简单封装，内置不实现并发机制，需要应用自己处理并发

Python 语言不以性能见长，这个结果不意外，你可以拿 go 和 python 跳过 taos 接口构造数据测试模拟一下语言层面的性能差异

尝试过了，在调用taos库获取的数据，速度是正常的，确实是cast花费了大量时间

try not use fetch_all_into_dict, use fetch_all instead

Sounds awesome. Can't wait to try it out
