Coordination Detection based on text similarity (cotweets)

[mrwunderbar666]

Implement "cotweets" (Keller et al 2020)

different accounts managed by a single person (or a team) can tweet the same message seemingly independently –
a pattern we will call co-tweeting. This type of coordination is probably most telling of an astroturfing campaign, because regular users are very unlikely to post the same message at the same time.

• Include simple version where tweet text is exactly the same
• Add feature for grouping tweets by text similarity.

there are some problems / improvements necessary:

1. add the skip_short parameter when calling TextReuseCorpus, otherwise it will ignore most tweets
2. forward keyword arguments to textreuse functions
3. ensure parallel processing is enabled and working
