• implemented more tolerant Flate decode with broken checksum

  reference identifying the widget (ISO 32000-1, Table 348)

Core library

• added support for Java 17
• added support for Java Platform Module System (JPMS)

CAUTION: the JPMS support required moving several classes into different packages:

• org.verapdf.pdfa.PdfBoxFoundry -> org.verapdf.pdfbox.foundry.PdfBoxFoundry
• org.verapdf.pdfa.PdfBoxFoundryProvider -> org.verapdf.pdfbox.foundry.PdfBoxFoundryProvider
• org.verapdf.pdfa.VeraFoundry -> org.verapdf.gf.foundry.VeraFoundry
• org.verapdf.pdfa.VeraGreenfieldFoundryProvider -> org.verapdf.gf.foundry/VeraGreenfieldFoundryProvider

These changes need to be applied to any Java source code that integrates veraPDF API as a Java library.
