• a new package
• an update for a package

0.5.6

• Require typst version >=0.13.0.
• Update cetz dependency to 0.3.3.
• Support CeTZ anchors on nodes which dynamically enclose other nodes (Support cetz anchors on enclose nodes Jollywatt/typst-fletcher#81).
• Allow nested enclosing of nodes (Allow enclosing nodes to be enclosed  Jollywatt/typst-fletcher#45).
• Add floating option to edge() to make certain objects not affect the diagram's bounds (Ignore labels when centering Jollywatt/typst-fletcher#38).
• Make debug annotations "floating" so they don't affect diagram size and layout.
