[Library]: Fixes (major: Parsing of organizations in result landing) & Addition of "FOS" and "SDGs" in result refine filters and result landing pages.

1. searchFields.ts: Added fos & sdg refine filters for research results.
2. resultLandingInfo.ts: Added string arrays "fos" and "sdg".
3. HelperFunctions.class.ts: Added method for sdg sorting (splits value, keeps only number before dot and compares numerically).
4. searchResearchResults.service.ts: [Bug fix] when parsing "dateofacceptance", stringify it only if it has a value.
5. searchFilter.component.ts: When sorting filters, sort differently SDGs.
6. resultLanding.service.ts:
	a. [Bug fix] Fix in parsing subtitle.
	b. [Bug fix] Parsing of "Related organizations" was accidentally deleted when parsing of relations changed.
	c. Parse "FOS" and "SDGs" in their specific fields, separately from subjects.
7. resultLanding.component.ts:
	a. [Bug fix] Do not make call for opencitations (deprecated).
	b. Updated method "hasPrimaryInfo()": Description is now array and added checks for organizations.
8. resultLanding.component.html: Display of "FOS" and "SDGs" separately from subjects.
9. showPublisher.component.ts: [Bug fix] Remove from html name of developer!
10. parsingFunctions.class.ts: Parse "FOS" and "SDGs" in their specific fields, separately from subjects.
11. metrics.component.ts: [Bug fix] Default value of "metricsClicked" should be false.
