chromium requires a custom format for hunspell dictionaries which they provide as blobs in an upstream repository. building from source (using convert_dict from the chromium monorepo and applying it to already packaged dictionaries) would not yield the same results (chromium packages adjustments to the dictionaries themselves) and would increase the maintainance cost. this patch adds a new hunspellDictsChromium attribute which includes dictionaries from chromium.
