Update environment_canada camera

[michaeldavie]

Breaking Change

The radar imagery used is no longer associated with fixed radar stations. As a result:

• The station and location attributes have been removed
• Entity names will change, as they are no longer related to the value of the station attribute

The integration can still be configured using a station identification code, so existing configurations using this method remain valid.

Proposed change

Use upgraded env_canada library:

• Removes use of web scraping for radar imagery
• Uses Government of Canada web map services to dynamically generate basemap and radar imagery for any Canadian location

Type of change

• Dependency upgrade
• Bugfix (non-breaking change which fixes an issue)
• New integration (thank you!)
• New feature (which adds functionality to an existing integration)
• Breaking change (fix/feature causing existing functionality to break)
• Code quality improvements to existing code or addition of tests

Example entry for configuration.yaml:

# Example configuration.yaml

  - platform: environment_canada
    latitude: 50
    longitude: -100
