Adding forecast capabilities to the Ontario, Canada parser

[r24mille]

Hello! I've been looking at the Ontario parser a bit. Neither fetch_consumption_forecast(...), fetch_generation_forecast(...), fetch_wind_solar_forecasts(...), nor fetch_exchange_forecast(...) have been implemented in the CA_ON.py parser. I believe the IESO has reasonable reports for these:

• fetch_consumption_forecast(...)
  • The Predispatch Constrained Totals.
• fetch_generation_forecast(...) and fetch_wind_solar_forecasts(...)
  • The Adequacy Report.
  • Although reports exist ~1 month into the future, only the current and next days contain the "Scheduled" element, which would be used as the data source (e.g. http://reports.ieso.ca/public/Adequacy2/PUB_Adequacy2_20211211_v72.xml).
  • The IESO states that the schedules for the next day are posted by approximately 11:15am. Anecdotally, I've seen "approximate" mean a little after 11:20am.
• fetch_exchange_forecast(...)
  • The Adequacy Report could also be used for imports/exports

I am willing and interested in developing this, if electricityMap would find value in it. Before sinking development time into it and opening pull requests, I wanted to confirm whether the maintainers of this repository would find value in those contributions. Thanks!

Hey @r24mille ! sorry for the long delay!

For something like this, I'd recommend you open an issue with the label "parser buildable". Discussions are oriented more towards larger ideas and methodological discussions.

If you have time and energy please go ahead and build these parsers :)
