16-bit BFP Square Root Depth

The function bfp_sqrt_s16() computes results one bit at a time, starting with bit 14 (the second-to-most significant bit). Because this is a relatively expensive operation, it may be desirable to trade off precision of results for a speed-up.

The time cost of bfp_sqrt_s16() is approximately linear with respect to the depth.

Defaults to XS3_VECT_SQRT_S16_MAX_DEPTH (15)
