v3.9.0

Changed:

• Support multiple output file groups for processors, #1344
  • OcrdPageResult: replace by proxy class OcrdPageResultVariadicListWrapper with list semantics and variadic constructor (with the original class now under SingleOcrdPageResult)
  • Processor.process_page_file: handle results from process_page_pcgts
    as lists:
    • split output_file_grp with commas (just as input_file_grp)
    • iterate over output file groups and OcrdPageResult
    • log error if there are more results than output file groups (that will get lost)
    • raise FileExistsError (in order to skip actual computation) iff output file exists for all output file groups
    • make output files (and file IDs), and save images etc for each output independently
• PAGE API: get_AllRegions available for all region types, not just PAGE root, #1344
• ocrd_network: Update RabbitMQ from 3.12 to (latest) 4.2, #1348
• ocrd_network: Fix and improve logging for network integration tests, #1348

Fixed:

• 🔥 do not log RabbitMQ credentials, #1346, #1348

Added:

• test combinations of OCRD_* config variables and multi-output, #1344
