Requested by @timsneath.. It would be useful to be able to view values in hex format in the variables view.

VS Code/DAP only work with strings so cannot provide formatting themselves, but the recommended way seems to be to contribute a context menu entry and handle it ourselves:

microsoft/vscode#28025 (comment)

This might need both work in the DAP and the VS Code extension (I'm also unsure whether this interacts with the ValueFormat in DAP spec, or if that's still VS-only).
