Tooling request: Visual Studio 2022 Extension

[olejsc]

Hi. Just leaving a note about a request for a Visual Studio Extension (not VS Code).

Description	Importance
Open d2 files	Must
Edit d2 files	Must
Save d2 files	Must
Live preview	Should
Export to SVG	Should
Export to markdown	Should
Syntax highlighting (intellisense)	Could

Just some of my thoughts on what the high-level requirements for a extension for visual studio community could look like.
