add task provider to run d2

[gavin-ts]

provide task to simply run d2 (e.g. on a file and create an svg right next to it (can use the preview settings for layout/theme etc))

maybe on a whole directory, or maybe to format the whole workspace

see https://stackoverflow.com/questions/55135876/extension-api-task-provider-build-task-example

[BarryNolte]

this should be relatively straightforward.

With PR #48, this task is complete

[gavin-ts]

#48 provides a command to run but a d2 render task could also be helpful in some cases

[BarryNolte]

Could you be more specific?

[gavin-ts]

vscode.tasks.registerTaskProvider vs commands.registerCommand

this has the same features but is different from #47 in that this is a command rather than registering a task provider that can be used e.g. from the tasks: run task command

d2task.mp4

Got it, should this even be available? Doesn't make much sense to me.

There's a lot of cool things that tasks support https://code.visualstudio.com/docs/editor/tasks
