🪲 [BUG] - s-split-words splits properly capitalized words like SPARCstation

[epakai]

Description

I have been using s-dashed-words to produce html anchor ids, and I noticed some extra dashes. In particular PCIe became pc-ie, and SPARCstation became spar-cstation. In testing I found the splitting came from s-split-words.

I found #43 where this was implemented. It seems aimed at handling camelCase words that also include all capital words (based on the provided example).

Steps to Reproduce the issue.

1. Call s-split-words on a partially capitalized single word: (s-split-words "SPARCstation")
2. Receive back two words: ("SPAR" "Cstation")
