Include custom data in call participant and call state

[Aanu1995]

1. Stream Video provide option to include custom data when creating user. However, in call participant, the custom data is not included, so there is no way to access the data.

2. In Backend via API call, there is option to include to include custom data when creating call. However, this data could not be access in call state.

Hi @Aanu1995, thanks for the feedback.

I can confirm that custom data were missing in CallParticipantState, and I already created a PR with the fix. It will be part of the next release.

As for the custom data in Call, it is accessible in CallDetails.
Here is an example of how to access it:

    final result = await call.getOrCreate();
    final metadata = result.fold(
      success: (success) => success.data.data.metadata.details.custom,
      failure: (failure) => throw Exception(failure.error),
    );

I'm closing the issue, but feel free to reopen it if you encounter any other issues regarding this.
