fix: Added useArtboardSize functionality

[Anas35]

Description

Added useArtboardSize functionality. This is quite different than rive_flutter's useArtboardSize.

In rive_flutter, when useArtboardSize is true then the artboard size is constrained by the parent constraints.
since RiveComponent use PositionComponent which does not depends on parent constraints, artboard size here can take as much size as it required.

I don't know If this is the right approach, Feel free to correct me If I'm wrong.

Lgtm, simple and clean :)

Hello thanks for the PR.

This can lead to an inconsistent API.

The field useArtboardSize is used only in the constructor. As people can still change the size of the component during its lifetime, we could have a scenario where useArtboardSize is true but the sizes are different

It seems hard to account for that, maybe it should just be called initializeWithArtboardSize or something that indicates that it only takes the artboard size on creation?

Yep, initializeWithArtboardSize could be one way to specify it, but It kinda gets redundant.

What about completely removing useArtboardSize and having the default value for size as artboard size? This would be breaking change only for those that didn't specify the size parameter.

Sounds like a good idea, since it'll be very few that haven't specified it anyways since the default is (0, 0).
