Swap out child_spawn with cross-spawn to address windows jadx path space

[Leapward-Koex]

This PR replaces the NodeJS default child_spawn module with cross-spawn due to command given to child_process.spawn failing if it has a spaces in it nodejs/node#7367.

Why?

Cross-spawn automatically handles commands with spaces.
This issue could be resolved by enabling shell and quoting the command but then we'd have to be responsible for command and argument input sanitization.

I've tested that this resolves issue #193 for me on Windows, I've also briefly verified that decompiling an APK and setting up the default git repository still works on a Ubuntu and Catalina machine.

Thanks @Leapward-Koex for the PR.
I am concerned that node-cross-spawn seems to be unmaintained for almost 3 years now. There are issues that aren't being addressed such as error on apple M1(I haven't verified this however).

Looks like a simple change but can we solve this in any other way with child_process?
