Make Anserini and Pyserini work fully on Windows

[lintool]

With WSL?

Making sure tests, etc. fully pass.

I will look into this.

Hello @lintool, I completed the task for both Anserini and Pyserini and made the pull requests. With WSL2, all of Anserini and Pyserini builds and tests work. (Anserini: castorini/anserini#2243, Pyserini: castorini/pyserini#1705)

Hello @lintool, I reformatted my changes correctly and created new pull requests for both Anserini and Pyserini (Anserini: castorini/anserini#2245, Pyserini: castorini/pyserini#1706). The issues with the changes in the last line of the files in the previous pull-requests were because of my VS Code auto-formatting, but I got that fixed now.

hi @gitHubAndyLee2020 I guess with WSL, everything seems to work fine on Windows? This seems much better than cywgin... previous users have complained a lot about failing tests, etc.

Just to confirm, python -m unittest works fine with Pyserini on Windows with WSL and everything works? (i.e., all tests pass?)

Hello @lintool. Yes, everything works properly with WSL2 on Windows, including python -m unittest (all tests passed).
