NPM Release 3.0.0

• Added synchronous function

Version 2.0.3

Minor Updates:

• values for N, r, p and dkLen are coerced into integers (if strings, for example, which was causing problems)
• no longer uses Buffer at all, so no requirement for the slowBuffer.

Version 2.0.0

• Now uses Uint32Array internally (instead of buffer)
• Other optimizations
• Requires an array/buffer-like object in, and returns an array; no buffer library required
