Refactor project path resolvers in CohortExtractor

[rkm]

Proposed Changes

• DefaultProjectPathResolver has been renamed to StudySeriesOriginalFilenameProjectPathResolver
• Undo handling UIDs with leading dot (Fix/cohort extractor output paths #1506) as this was causing difficulties with path lookups elsewhere
• Add StudySeriesSOPProjectPathResolver which generates filenames using SOPInstanceUID instead of the original file name. This is now the default path resolver
• Disallow null Study/Series/SOPInstanceUID values, which should never occur in practice

Types of changes

• Bugfix (non-breaking change which fixes an issue)
• New Feature (non-breaking change which adds functionality)
• Breaking Change (fix or feature that would cause existing functionality to not work as expected)
• Documentation-Only Update (if none of the other choices apply)
  • In this case, ensure that the message of the head commit from the source branch is prefixed with [skip ci]
