Description

The purpose of this PR is to enable testing of TileServer integration on the pp-irt. In prod it should work the way it works now. Once testing and fixes are performed the redis integration will be enabled in prod.

To test it locally:

Add to server config:

{
  "redis" : {
    "url": "redis://localhost:6379",
    "secret": "generate_some_secret"
  },
  ...
  
  "tileServerURL": "http://localhost:5000",
  "tileServerMount": "/path/to/tp"
  }

Install redis:

  brew install redis
  brew services start redis

Test it works:

redis-cli
PING

If Redis is running, it will return: PONG

Set up TileServer like explained here:

TissueImageAnalytics/tiatoolbox#897

Generate a fsspec JSON file like explained inside of the PR.

Change tileserver.py code to:

from flask_cors import CORS
from tiatoolbox.visualization import TileServer

# Initialize and run the TileServer
tile_server = TileServer(
    title="Tiatoolbox TileServer",
    layers={},
)
CORS(tile_server, send_wildcard=True)


tile_server.run(host="127.0.0.1", port=5000)

Start the TileServer like:

python3 tileserver.py

Place JSON file inside of:

/path/to/tp/hg38/gdc/wsimages/73c69d24-6f9e-44e2-bfe5-a608d4cf5c27/73c69d24-6f9e-44e2-bfe5-a608d4cf5c27_fsspec.json

It works after setting up redis, tiileserver, and other dependencies. Super fast zooming and panning.
