v7.0.0

What's Changed

• Upgrade Emscripten to 4.0.15 by @fanchenkong1 in #49
• Created new "Relaxed SIMD" build (#46)
  • This build allows supported devices/runtimes to use the fastest CPU instructions (see here for description of feature).
  • This feature is not yet supported on all devices (see browser support here)
• Implemented optimizations to existing SIMD build (#46)
• Various minor updates

Thanks to @fanchenkong1 for implementing the substantive changes in this release. The various changes produce a 20%+ improvement to runtime on certain devices.

Note: 6.1.2 is identical to 6.0.0. The versions between 6.0.0 and 6.1.1 are the same substantive changes that ended up being included in 7.0.0. These ended up being breaking changes as they did not run in Node.js 14, so had to be rolled back and put into a major release.
