Review Comment:
This widens `cp` a bit. The old pattern was `^[A-ZÄÖÜ]\.$`, but
`Character.isUpperCase` accepts capitals from any script. So `É.`, `Ñ.`, etc.
change from `ic` to `cp`, and supplementary-plane capitals change from `other`
to `cp`.
That changes the features existing NameFinder models see for non-English
text. Could we limit this PR to `A–Z` plus `Ä`/`Ö`/`Ü` and propose the Unicode
change separately?
Open to other ideas, too.

> Key: OPENNLP-1975
> URL: https://issues.apache.org/jira/browse/OPENNLP-1975
> Project: OpenNLP
> Issue Type: Bug
> Reporter: Richard Zowalla
> Assignee: Kristian Rickert
> Priority: Major
> Fix For: 3.0.0
>
> Time Spent: 1h 20m
> Remaining Estimate: 0h
>
> Split out of OPENNLP\-1928 \(PR #1275\). Depends on OPENNLP\-1928 \(RegEx
> removal part 1\).
> Replaces the regular expressions of these sites with scans that follow the
> intended format instead of copying the regex quirks. The output changes:*
> {{TokenSampleStream}} \(English\): tokens are split on Unicode White\_Space;
> a leading space no longer yields an empty first token; a line without a token
> resets the open\-quote state; a token with a letter or digit of any script is
> a word.
> * {{ParserTool}}: brackets that follow each other are each separated
> \({{a\)\)b}} gives {{a \) \) b}}\).
> * {{ConlluStream}}: a malformed multiword token id \({{3\-}}, {{\-4}},
> {{3\-\-4}}, {{1\-2\-3}}, {{4\-3}}\) fails with an {{InvalidFormatException}}
> naming the id.
> * {{DownloadUtil}}: a blank checksum file is an {{IOException}} saying so.
> * {{FeatureGeneratorUtil}}: the {{cp}} class requires exactly one capital and
> one period.
> Before merge: tokenizer eval build that reads through {{TokenSampleStream}}.
