> Adds a stemmer implementation that reads standard Hunspell {{.dic}}/{{.aff}} dictionary pairs, built on the {{StemmerFactory}} seam introduced in OPENNLP-1883.
> Supported affix features:
> * alias compression (AF)
> * NEEDAFFIX
> * ONLYINCOMPOUND
> * FORBIDDENWORD
> * CIRCUMFIX
> * compound word positioning, including linking forms as used in German compounds
> Parsing is regex-free, and unsupported dictionary features fail loud at load time rather than degrading silently. Dictionaries are user-supplied; nothing is bundled. The manual gains a section whose example is asserted by a test.
