Review Comment:
An alternative to `synchronized` would be to re-create and dispose the
`DictionaryLookup`, which is " is cheap to create and dispose (so it makes no
sense to cache)" according to
https://github.com/morfologik/morfologik-stemming/issues/69, i.e. moving to
```java
List<WordData> dictMap = new
DictionaryLookup(dictionary).lookup(word.toLowerCase());
```
and just store the (thread-safe) dictionary in the `MorfologikLemmatizer`
instead of the not thread-safe `DictionaryLookup`.
That would avoid the synchronization cost. Wdyt?
