refactor: switch to fast-glob

This removes `node-glob` in favor of `fast-glob`. The main motivation for this is because `node-glob` has a security warning and I can't update to `node-glob@9` unless we drop compatibility for node v8. Switching to `fast-glob` seems to be fairly straightforward, although some options need to be changed by default for bash compatibility. Fixes #828 Fixes #1149
