Compared the yesterday's crawling data with this one, the location of the stops are shifted by a little bit, something like:

-    "lat": 22.242937061229764,
-    "lng": 114.14820494490924,
+    "lat": 22.24293706134395,
+    "lng": 114.14820494452849,

Also changes of stop names and routes, as usual.

Redo the comparison with https://github.com/hkbus/hk-bus-crawling/actions/runs/10975036174, the following differences were found:

1. some stop names are changed, but both names seem to describe the same place
2. stops lat and lng are changed a little bit, spot checked several of them, only start to differ after 8-9 decimal place.
