Support shortcut for starting manimgl interactively based on current line

[Splines]

Such a command (with an assignable shortcut) could do the following

Steps

• Launch a new terminal in a floating window
• Execute manimgl with params based on the which line the cursor is in, that is
  • Find out in which file the cursor is (probably easy), e.g. path/to/file.py based on the current directory where VSCode is open
  • Find out in which python class the cursor is (probably a lot trickier, maybe pylance provides kind of an API for this?), e.g. SceneName
  • Find out the current line number (probably easy), e.g. 42
  • Pass everything as mangiml path/to/file.py SceneName -se 42

Additional

• Before doing all of this, check if there isn't already a terminal open. If there is none open, do the steps above.
• If there is already a terminal open: somehow check if manimgl was already launched in interactive mode (in any of the open terminals).
  • If yes: is there a way to restart it on a new line number? For this case, it is maybe easier to just kill the active session and open a new one. However, this would have the disadvantage that the window position of the OpenGL popup is lost.
  • If no: just start it as described above.
  • Special case: what if multiple terminals run manimgl? Should probably report an error in this case.

Argh, I would really like to have this functionality as part of the extension before I publish this extension's awesome recent developments (thanks you both!) to the marketplace. However, after doing some research the CC-BY-NC-SA license is not compatible with the MIT license I am currently using. We have two options:

1. We can implement our own logic from scratch, without inspiration from the original implementation. Or,
2. We can update the extension's license to CC-BY-NC-SA

I believe this is a very important feature to have as part of the extension. Let me know your thoughts

Hi!
Really awesome contributions from @Splines !

I believe Grant has allowed to use the workflow itself without the CC license.

Oh sick. Let's get this functionality implemented then. Do you want to prep the PR against main?

Yes: #17
