Trim distribution size

This package is a hefty ~25 mb on disk! About 90% of that is .obj and .pdb files in the build folder that are not needed outside of development. The install script should be modified to delete extraneous debugging files after building.

I think Barry may have abandoned this project. If you are using Node.js v10.5.0+, you could try my scrypt-kdf, which is a simple pure-JS wrapper around the native OpenSSL implementation of scrypt. If you try it, I would be interested to know whether you have any issues.

Unfortunately, I am limited to Node 8.10 thanks to AWS lambda. However, if I need scrypt functionality in a future project, I will be sure to consider your library.

@jonhartnett if it's still of interest, scrypt-async can be used as a polyfill for the OpenSSL scrypt, to enable scrypt-kdf to be used with Node.js prior to 10.5.0 – there is an explanation in the README.
