KWS unit test switched from bit exact checking to Noise to Signal ratio checking.
Most of the double precision floating-point operations in SpeexLib library code replaced by single precision.
Changes in unit test to clarify the use of Noise-to-Signal ratio instead of Signal-to-Noise (SNR) ratio.
Documentation update: Score calculation formula uses 1/1.5 scaling rather than 1*1.5.
Documentation update: Clarify that only float version of SpeexDSP is supported.
Documentation update: KWS unit test description (changed to use Noise-to-Signal ratio).
Other minor documentation improvements.
