Update parsing to the new collection dates page

[LaurenceGA]

Hey. I went to use this and found it was broken.
So I forked it and updated it to properly parse the new front end "new.aucklandcouncil.govt.nz".

Also added a dev container and removed the trailing slash from the endpoints which I think is more conventional (I got stuck on this for a while).

Also updated the home assistant bit to use rest instead of sensor.rest, so it will just make a single call to the API.

Anyway, I updated the unit tests, tested locally, and have it working integrated into my Home Assistant.

[LaurenceGA]

Awesome, thanks for merging. Will you so a release?

[rusq]

Done!

(Inb4 - pushed a tag blissfully, forgot that there's no release action on this repo.)

Hi Laurence, thanks for fixing this! It's been broken for a while now. I just recently updated the container when I saw this update but I'm still getting an error. Do you guys know what this is about? When I try to do the default command

curl --location --request GET 'http://192.168.1.243:5015/api/v1/rr?addr=500%20Queen%20Street'

I get the result

{"error":"invalid character '\u003c' looking for beginning of value"}#

Hi @SkillzWhoKillz

Just looked in to it.
Oof, yeah, looks like they broke it again and have changed their property search API.

Raised a PR to fix: #22 @rusq 🙏
