[PD] maxlib arraycopy

[Matt Barber]

Fastest vanilla way now is to get the range from the source as a list with
[array get] and then write to the dest with [array set]. It's faster than
you'd think. You can do some minor bounds checking, but the way Pd ranges
work mostly takes care of that for you.
