readDeltaVarintsInto for values known to fit in 32 bits, such as a
chunk's codes at max_depth 16 and under: a running total that
outgrows the Uint32Array is a format error, not a silent wraparound.
A separate function rather than one taking either array, because V8
optimizes a loop for the array types its function has seen, and a
loop that has seen both decoded chunks ~10% slower.
