Move `compas-save`

[JakobVogelsang]

To be able to use OpenSCD core we need to move out heavily used web-components within CoMPAS. This issue shall describe how to move out compas-save

t.b.d

[Stef3st]

Acceptance criteria:

• Remove all compas-save code from compas-open-scd
• Compas-save and save-as plugins are basically the same. This needs to be rewritten
• Components should be UI based only. So no logic to it
• Plugins should contain logic and should use the UI component
• Tests need to be rewritten accodingly
• Dependencies are imported from their own repositories.
• Check to see if helper files are only being used for this particular plugin, if so move to repository. Otherwise, figure where it should be implemented and import dependancy. ( Do not include “compas-core” in the repo)
• Include screenshot tests if needed
• Document the new API of the plugin
• Add TypeDoc for documentation to the repository
• Create storybook for the plugin

TBD:

• How to handle translations
• How to handle logging
• Save-as-version now opens the entire document just to be rewritten. This needs to be refactored so it only uses the document ID

OSCD new architecture/logic can be re-used to build this: https://github.com/openscd/oscd-new/tree/oscd-new_WIP

After pair sessions with @Stef3st it was decided to have code duplication instead of using the CompasExistsIn mixin, because it was problematic to have it exported and reused in multiple plugins (CompasSave and CompasUploadVersion).
