Specifying openmeteo model

[mglisse]

Hello, thanks for providing this extension.
Open-meteo has a nice model for my location (around Paris) from meteo-france. Sadly, best-match picks a different model that is wildly inaccurate even for the current weather. I compared the 2 using "try the API here" on the open-meteo.com website.
I see that the extension has some code related to this, but I couldn't find a way to specify it in the preferences of the extension. Using dconf-editor to add ,"omModel":"meteofrance_seamless" to the location only managed to produce

TypeError: can't access property "i", fIcon is undefined

in providers/openmeteo.js.

Could you document a way to specify the model (without editing the extension)?

It looks like I get the same error if I edit the extension, the problem seems to be that meteofrance_seamless only provides 3 days of forecast (4 counting today), whereas the extension assumes it has access to more. So request n°2 (I can file a separate issue if you prefer) would be to make the code robust to this situation, not prevent the whole extension from running just because the forecast for many days in the future is missing.

This would maybe be something I'd consider supporting in the future, however it's not officially a "supported" feature as of right now. The only reason this was originally added was because of a similar issue happening in New York in #100, and I found that changing the model there didn't really help much so never fully implemented it.

It's useful to know that this issue is happening in another location though and I will look at fully adding it if it would be useful.

I did some minor patching to use dummy values when the forecast doesn't have enough days, which was enough to avoid the TypeError, and so far I am satisfied with the weather meteofrance_seamless shows, though it hasn't been long enough to be sure.
So I think my second request (gracefully handle too few days of forecast) is the one I care about most now, so the extension keeps working when my system decides to update the extension.
I understand that the best would be if I could get openmeteo to have best-match use meteofrance for the days where it is available...
