Related issue: #60 Related PR: #63 The [thread IDs](https://github.com/gaogaotiantian/coredumpy/blob/31becdc08169513999713d6ef61c001c658ce6c3/src/coredumpy/dap_server.py#L154) in the dap server weren't converted to lower reference IDs. I might be wrong, but it looks like [the thread ID can be an unsigned long long](https://github.com/python/cpython/blob/366a7902a000423988cbcece40f8264797610de6/Modules/_threadmodule.c#L630), which means it could be larger than $2^{31}$.
