[FEATURE] Create Processing's own terminal

[IamPhytan]

Is your feature request related to a problem? Please describe. I can't build projects through extension's command processing.RunTaskFile. Each time I try to run it, no integrated terminal shows up, therefore no output appears. This may be caused by the fact that the Terminal doesn't gets called by the extension.

I can use the Keyboard Shortcut for Run Build Task to run it, but it would be great to have a keybinding only for running Processing projects.

Describe the solution you'd like I suggest implementing a terminal that would be for running Processing files only, like this extension found a way to run MATLAB from VS Code in a desgnated integrated Terminal.
