Close zipfile before removing

Hi,

could you please consider the following patch to close zipfile before removing it, while unzipping.

It appears as if windows 7/10 is holding a handle to the open zip file, and as such can't remove it before is being closed.

For example, when building plotly from cljsjs/packages on windows (either 7 or 10), the following error is thrown:

.../cljsjs-packages/plotly $ boot package ... Downloading v1.45.3.zip ... Extracting 2873 files java.lang.Thread.run
