[TypeScript] Offer a way to parse typed arrays in flexbuffers without copying

[mstange]

I have a flexbuffers file where the majority of its contents is stored in very long arrays of integers.
My original file data is in a Uint8Array.
I would like to get access to the long arrays without having to incur a copy.

Does the TypeScript flexbuffers implementation offer a way to get a, say, Int32Array which just wraps the original buffer?
