Accomodate Nuspell by putting the dictionary dir in its own subpackage

Given that itʼs compatible with Hunspell dictionaries, package `nuspell` requires `hunspell-en-US`, which in turn requires `hunspell`.  It doesnʼt seem right that installing one spellchecking backend should cause a different one to be pulled in, so this commit seeks to break that chain by giving the `/usr/share/myspell` directory a package of its own.
