Fix: use github.com instead of nodeload.github.com for downloading zips

[jaxrtech]

There seems to be an unavoidable SSL issue with downloading repo ZIPs from https://nodeload.github.com.

I've modified the code to instead download straight from https://github.com/$USER/$REPO/archive/$TAG.zip (this uses the same link format as the "Download ZIP" on the website itself).

This more importantly was causing issues upstream with running truffle init (see issue).

The only other changes where making extractZip unzip directly to the target directory, and updating dependencies which were causing npm audit issues.

This also avoids getting an error: EXDEV when trying to rename between devices. In other words, with respect to the test cases, trying to rename the relative './$TIMESTAMP/' directory to '/tmp/test-github-download/1/', for example, would fail with EXDEV if /tmp is a separate device mount on the machine (which is the case on my machine).

Please feel free to let me know if there should be any additional changes made to this PR. Or if anything needs any clarification.

Thanks!

A friend of mine was experiencing this issue as well when using Truffle. I had no issues with

curl https://nodeload.github.com/ 

however he was getting SSH issues which preventing truffle from working
