Add future verb extraction to actions widget

[ThijsVroegh]

In addition to the currently available past and present verbs, future verbs need to be added (i.e., future present). In Dutch, this refers to the "onvoltooid tegenwoordige toekomende tijd". For this, we need to consider the groupings of verbs: 'auxilary verb 'zullen' together with the 'infinitief' (i.e., hele werkwoord). We then cover the complete scope of past, present and future.

Example:

One example with regard to the identification of the future, we could make a simple rule to classify a sentence:
Future tense = yes if lemma of the auxiliary verb (AUX) in the pv (persoonsvorm)= zullen and this verb is related in head to an infinite verb later in the sentence. (based on https://e-ans.ivdnt.org/topics/pid/ans02040805lingtopic)

doc = nlp(“Ik zal naar Frankrijk gaan”).
for token in doc:
print(token.text, token.lemma_, token.head, token.pos_, token.dep_, token.tag_, token.ent_type_)
