Investigate adding a license checker for built wheels

Right now, part of the wheel build review process has always involved downloading a built wheel, unpacking it, and inspecting it for:

1. The project's LICENSE files and related data
2. The presence of linked libraries included in the wheels as part of the final build process
3. Any license compliance steps which needed to be taken based on the libraries found in step 2 (if any)

It would be very helpful to have this check automated along with everything else we've got running for every PR. However, while checking for the correct license according to the target project may be simple, having the workflow/script confirm that we aren't missing any supplemental licensing (or, possibly, that the wheels are actually failing to meet licensing requirements) is going to be more complicated.

首先检查现有的 workflow 或脚本，该 workflow 或脚本会为每个 pull request 构建 wheels，然后检查构建出的 wheels 中是否包含 LICENSE 文件和捆绑的库。定义应如何报告补充的许可和合规性发现；当自动化检查能够在 pull request 构建期间可靠地识别这些情况时，工作即完成。
