* Add wasm code * First working model * Add PixelManipulation web assembly code to browser and node * Tests corrected for modules * Corrected test script * Add wasm bechmarks * Update Readme * Applies toggling functionality and refactored PixelManipulation code * Added documentation and corrected wasm toggling * change noise reduction module to use wasm code * Corrected formatting and removed extra comments * Add default wasm option and made README changes * Fixed negative test timings * combined benchmarks file * Update benchmark.js * Removed copies of wasm file and corrected test format * Update package.json Co-Authored-By: Jeffrey Warren <jeff@unterbahn.com> * Added wasm file and removed redundant code * Removed earlier benchmarks * move test/core/sequencer/benchmark.js to its own test command, not passing to tape-spec * Solves memory leaks and blank lines * Solves memory leaks and blank lines * Added handler for node code * Modify test script * Modify test script * Correct doc and removed pace fuctionality
