Motivation

This is related to

and adds a additional safety measure to avoid issues related to Buffer, specifically we wanna avoid unexpected behavior such as Buffer.prototype.slice not copying memory.

Description

This changes ensures loaded state is typeof Uint8Array by converting loaded bytes. This operation is pretty much free based on benchmarks in #6688 as it does not copy the underlying memory, just updates the view.

Buffer utils
✔ Buffer.from - copy                  7.286412 ops/s    137.2418 ms/op   x1.024         38 runs   5.82 s
✔ Buffer.from - no copy                1117318 ops/s    895.0000 ns/op   x0.982     723013 runs   1.11 s
✔ Buffer.from - no copy with offset    1179245 ops/s    848.0000 ns/op        -    2699558 runs   3.85 s
