investigate memory machinery optimisation with prepack/closure compiler

[Bnaya]

https://github.com/Bnaya/objectbuffer/blob/develop/src/internal/memoryMachinery.ts

The memoryMachinery stuff adding few layers of indirection on top of typedArray to provide something that is similar to C structs

Most of these indirections can be replaced with flat code, that probably gonna be more performant.

prepack / closure compiler might we able to reduce some of the indirections, maybe after some changes

#86 + the terser minify inline the structs access very nicely,
But there are other things we can achieve from better inlining
This issue is absolute, need to open more up to date one

Mostly inlined
