Add Audio Clip and Buffer Options to Haptic SDK

[ddugganCRA]

Our current Haptic SDK has a limited sampling rate as it only provides a single intensity for each time step. This allows even the most basic haptic systems to work with VSDK, but we want to be able to take advantage of systems that let us push buffers as well. Additionally, we should add Audio Clip support as an alternative to Intensity Curves in the haptic patterns.

• Add optional parameters to the StartHaptics function: an Intensity Buffer as an array of float values and the sampling rate the array represents
• Add Audio Clips as an alternative to Intensity Curves in the haptic pattern interface
