> The current synonymsfilter uses a lot of ram and cpu, especially at build time.
> I think yesterday I heard about "huge synonyms files" three times.
> So, I think we should use an FST-based structure, sharing the inputs and outputs.
> And we should be more efficient with the tokenStream api, e.g. using save/restoreState
instead of cloneAttributes()
