Tree-wide: Fix Windows build

[daviessm]

I don't have a Mac to test on, I'd appreciate it if someone could check that build out too. This branch currently builds on both Windows and Linux.

Fixes #169
Fixes #102

Looks like this failed on MacOS https://github.com/eza-community/eza/actions/runs/5991795977/job/16263711309?pr=171

I added windows to the CI, so when windows support is working and this merges, it will keep working (hopefully).

Thanks @cafkafk, I pushed a couple of fixes but without a Mac I'm shooting in the dark. Can you give the CI another run (probably just the macos one, if that works then the rest can run as well)?

[cafkafk]

This merges the #173 changes in, so we can ensure they also work on windows.

[cafkafk]

CI passes, and initial testing on x86_64 GNU/Linux indicates this is working as expected. Can someone verify this works on Windows/Mac?

[daviessm]

Windows build looks fine to me. Perhaps @cfxegbert could test this branch on Mac?

[cafkafk]

I guess we'll just test this live, I feel like it's reasonable to expect it's also working on mac, if not people will probably be quick to open an issue about it.
