Given an iterable that yields (current, maximum, status) tuples, rescales current and maximum
to fit within the range [start, end]. `current` is assumed to start at zero.
Use rescaleProgress to combine multiple progress-yielding iterables by assigning
a different range to each iterable.

Iterate through a collection, yielding (progress, value) tuples. `progress` is the value
