feat: generic slice 'take' function

[meowgorithm]

Take returns a sub-slice containing at most N items from the head of a slice. I know Go’s not tail-call optimized, but I can still see this being handy.

I wonder if calling this Head makes sense, which would allow us to also introduce Tail to "take" the last N elements of an array?

Another name pairing could be First and Last.

I think Head and Tail make a lot of logical sense, though in FP head usually returns a single element and tail returns a list of everything except the first item, so I'd be concerned about confusion there. Take is also a known FP term for getting the first N items.

Perhaps TakeHead could be an alias for Take and then TakeTail could take N item from the end.

Ah, cool. I didn't know about this. Then this makes sense to me for sure!
