Add CrossRefCitationFetcher

[koppor]

Makes use of CrossRef's capability to fetch citation information

Example: https://api.crossref.org/works/10.47397/tb/44-3/tb138kopp-jabref

Not wired into the GUI for our citations tab. This can be a good-first-issue as follow-up.

Steps to test

./gradlew :jabkit:run --args="get-cited-works --porcelain 10.47397/tb/44-3/tb138kopp-jabref"

Alternatively, run org.jabref.logic.importer.fetcher.citation.crossref.CrossRefCitationFetcherTest

Mandatory checks

• I own the copyright of the code submitted and I license it under the MIT license
• I manually tested my changes in running JabRef (always required)
• I added JUnit tests for changes (if applicable)
• I added screenshots in the PR description (if change is visible to the user)
• I described the change in CHANGELOG.md in a way that is understandable for the average user (if change is visible to the user)
• [/] I checked the user documentation: Is the information available and up to date? If not, I created an issue at https://github.com/JabRef/user-documentation/issues or, even better, I submitted a pull request updating file(s) in https://github.com/JabRef/user-documentation/tree/main/en.

[Siedlerchr]

enum values should be UPPERCASE

[koppor]

I wasn't sure if it works with picocli

./gradlew :jabkit:run --args="get-cited-works --provider=semanticscholar --porcelain 10.47397/tb/44-3/tb138kopp-jabref"

Invalid value for option '--provider': expected one of [CROSSREF, SEMANTICSCHOLAR] (case-sensitive) but was 'semanticscholar'

Fixed in f5544da - 39 lines of code ^^

[Siedlerchr]

tools.jackson to avoid the same issue as in the Unpaywall fetcher

[koppor]

IntelliJ auto import 🙈
