fix: adds both funding capture and posted_content doctype to crossref parser

[seasidesparrow]

• Bumps ingest_data_model requirement to v1.0.9 (which adds fielded funding information)
• updates base parser to populate funding element
• updates crossref parser to capture posted_content doctype
• implements funding capture in crossref.py (works for all crossref records with funding info, not just posted_content doctype)
• adds posted_content doctype records to test_crossref.py and updates existing tests to capture funding info where available
