BitMagic release v7.4.0

1. Continued effort to provide better version for WebAssembly, first WASM SIMD build is available using:
   #define BMWASMSIMDOPT (or define via makefile).

emcc command like may look like:
emcc -std=c++11 -s ALLOW_MEMORY_GROWTH=1 -O2 -msse4.2 -msimd128 -D BMWASMSIMDOPT -s WASM=1 -s DISABLE_EXCEPTION_CATCHING=0 -fno-rtti

Please note that WebAssembly SIMD is implemented as cross-compilation tweak for SSE4.2 (thus needs -msse4.4 flag).

WebAssembly SIMD is still an experimental feature for all browsers but Google Chrome.
Initial performance observations sometimes show faster than native(without SIMD) speed for optimized algorithms.

2. Implemented 3-valued logic operations (INVERT, AND, OR) following the Kleene truth tables.

3. Fixed bugs in parallel algorithms (race condition).
