Support path for scale and translation

[jwindhager]

According to the OME-Zarr 0.5 spec, scale and translation vectors are...

stored either as a list of floats (scale, translation) or as binary data at a location in this container (path)

In comparison, the current Scale and Translation models seem to only support lists of floats:

ome-zarr.js/src/types/ome.ts

Lines 119 to 127 in b181746

	export interface Scale {
	type: "scale";
	scale: number[];
	}
	export interface Translation {
	type: "translation";
	translation: number[];
	}

Hmmm - I wonder exactly what binary data at a location in this container means? In RFC5 the path is specified as zarr array at a location in this container. But "binary data" is less clear?

No clue 😅 Not sure anyone is currently using path, just opened this issue to keep track of it.
