addded FlaggedDiskObject and reworked CachedDiskObject to make it cross compatible with FlaggedDiskObject, and thus create a CachedFlaggedDiskObject class using both functionalities

adding load_requirement ability to scan through kwargs to output what it needs, if the arg is present, or not

adding more tests to support the three pipeline creation strategies and to test requirements processing

changes to pipelines to use typehinting for dynamics attributes (but not very well done. Might remove this later if it causes more isses than it helps)

updating to use pdm as build backend + docstrings for every function (ai generated for now, need to check) + bump version
