Enhance open Trace from arrayBuffer peformance When we opened a trace from an arrayBuffer, we used '.slice(start,begin)', that creates a copy of the array each time. Using 'subarray' we save this copy. the new Uint8array created points to the same 'ArrayBuffer' of the original UInt8array, but with a different offset and length.
