Dirkjan Ochtman 85f4f94b53 Use more efficient segmentation strategy 
Based on the triangular matrix approach as explained here:

https://towardsdatascience.com/fast-word-segmentation-for-noisy-text-2c2c41f9e8da

Use iteration rather than recursion to segment the input forwards
rather than backwards and use a `Vec`-based memoization strategy
instead of relying on a `HashMap` of words. This version is about
4.8x faster, 100 lines of code less and should use much less memory.

Dirkjan Ochtman 2d942bbfc9 Box up the BitVec array 
The `Search::best` field will take about 8000 bytes. In some of our usage
with rayon, this appeared to cause stack overflows. Boxing it up makes the
code slower by about 1-2%, but should hopefully avoid stack overflows.

Now that the core crate is in a directory, we no longer needlessly publish
data files on crates.io.
