Update fife_gov_uk.md

Thank you so much for your work adding Fife to the tool.  I've added a more advanced example that features Fife's bin type names and a quicky example of sensors for them too.
I noticed that you include a type for bottles in your code, though I'm not aware of a bottle collection.  Happy to add to the example though if this is the case :)
I've also added the yaml I used to create a widget on my dashboard.  I just thought it a nice example and wanted to share what I was using but do say if you feel this isn't appropriate here.

+### A more complete example with a dashboard card
+
+Here's a more complete example of the sources that adds pictures and shorter names to the types that come back from Fife's API:
+
+```yaml
+waste_collection_schedule:
+  sources:
+    - name: fife_gov_uk
+      args:
+        uprn: "320069189"
+      customize:
+        - type: "Food and Garden Waste / Brown Bin"
+          alias: "Brown Bin"
+          picture: https://www.binfactoryoutlet.co.uk/wp-content/uploads/2020/06/240L-Brown.jpg
+        - type: "Landfill / Blue Bin"
+          alias: "Blue Bin"
+          picture: https://www.binfactoryoutlet.co.uk/wp-content/uploads/2020/06/240L-BLUE.jpg
+        - type: "Paper and Cardboard / Grey Bin"
+          alias: "Grey Bin"
+          picture: https://www.binfactoryoutlet.co.uk/wp-content/uploads/2020/05/240L-ANTRACITE.jpg
+        - type: "Cans and Plastics / Green Bin"
+          alias: "Green Bin"
+          picture: https://www.binfactoryoutlet.co.uk/wp-content/uploads/2020/06/240L-Green.jpg
+  day_switch_time: "18:00"
+  
+```
+
+Once you've done that, you can add sensors for each bin using just those short names:
+
+```yaml
+sensors:
+  - platform: waste_collection_schedule
+    name: Next Bin Collection
+    add_days_to: true
+  - platform: waste_collection_schedule
+    name: Next Blue Bin Collection
+    add_days_to: true
+    types:
+      - "Blue Bin"
+  - platform: waste_collection_schedule
+    name: Next Brown Bin Collection
+    add_days_to: true
+    types:
+      - "Brown Bin"
+  - platform: waste_collection_schedule
+    name: Next Grey Bin Collection
+    add_days_to: true
+    types:
+      - "Grey Bin"
+  - platform: waste_collection_schedule
+    name: Next Green Bin Collection
+    add_days_to: true
+    types:
+      - "Green Bin"
+    
+ ```
+
+And finally, you can use those sensors with an entity-filter card to produce a widget that shows a picture of the upcoming bin collections this week:
+
+```yaml
+type: entity-filter
+entities:
+  - sensor.next_blue_bin_collection
+  - sensor.next_brown_bin_collection
+  - sensor.next_grey_bin_collection
+  - sensor.next_green_bin_collection
+state_filter:
+  - operator: regex
+    value: \s(0|1|2|3|4|5|6)\s
+card:
+  type: glance
+  show_name: false
+  show_state: true
+show_empty: false
+
+```
