Tiled and Websocket listeners and publishers

[dylanmcreynolds]

As we have developed arroyopy features in other projects, I think we should consider moving a few listeners and publishers into the main arroyopy.

Tiled

Both the XPS and SAS experiments have needs for a frame publisher to publish to Tiled. Currently, one lives in the Latent Space Explorer repo. This version is fairly specific the LSE. I think we should maybe move most of that code here into arraoypy. The LSE version has a lot of custom code for deciding where in tiled to put each frame. I propose the following:

1. In arroyopy, a generic TiledFramePublisher class. But it contains an overridable _get_tiled_path() method.
2. In LSE, we have a class that overrides the arroyopy class:

class LSETiledFramePublisher(TiledFramePublisher):
  
  def _get_tiled_path(message: FrameMessage) -> Tuple[List[str], str]:
       """ Do some calculation on where in tiled to put this frame
             Return is a Tuple of location and slicing information 
       """

The return value is a little awkward, maybe we create a class that defines the path segments and enough information to patch an existing array with the new frame.

WebSocket

In LSE, there's a web socket listener

In XPS, there's a web socket publisher

Both of these probably can be generically added to arroyopy here, with minimal overrided code in the specific projects.
