deepTransform
Transforms a recursive iterable by a given function. Works like deepMap but
allows you to stop transforming at any point of the tree. The traversing
happens depth first.
deepFind
Goes over every `{ key, value }` of a recursive iterable data structure (for
arrays being numeric key and the value at the key position), and uses a function to extract
elements at any point in the tree onto an array that is returned. If a third
argument, the limit, is provided, it will stop iterating as soon as the number
of found objects reaches that limit.
Why?
Because this will allow me to find the first two nested occurrences of a terms
object with a field property and to modify the first so that it has:
`collect_mode: 'breadth_first'`
More abstract universal [foldWhile](#58), for infinite reducers.

Studied a bit and found out that the foldWhile/flowReduce were an implementation of an automata, a finite state machine, but with non-deterministic data structures and an unbounded number of generators... which is generalized in Category Theory as the Groupoid Category. See https://en.wikipedia.org/wiki/Automata_theory#Connection_to_category_theory
This implementation satisfies exactly the same tests as flowReduce, but is completely stripped of lodash utilities for clarity.
The name is particularly tempting since is easy to pronounce, funny enough to remember, and technically precise 😱
Please review 😻
