• Introduce S.serializeWith function with Safe and Unsafe modes
• Remove S.constructWith in favor of S.parseWith(~mode=Unsafe, struct)
• Remove S.destructWith in favor of S.serializeWith(~mode=Unsafe, struct)
• Introduce S.json struct factory
• Remove S.parseJsonWith in favor of S.parseWith(S.json(struct))
• Remove S.serializeJsonWith in favor of S.serializeWith(S.json(struct))
• Add S.transformUnknown function for more convenient work with S.unknown struct factory
• Renaming public functions of the MakeMetadata module
• Add undocumented S.refine function. It's an alpha version, that has a hight chance to be changed in next releases.
