Play the count of plays of the GIF to the count of plays of the GIF itself.

Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is.
I want to play the count of plays of the GIF to the count of plays of the GIF itself.
For example, the built-in count of plays of GIF is 3, and I want to play the corresponding count, and I don't want to set a repeatCount by ImageRequest, but if I don't set it, the default repeatCount will be REPEAT_INFINITE, this is not what I want.

Describe the solution you'd like
A clear and concise description of what you want to happen.
I want to play the built-in count of GIF without manually set a fixed count of playback times.

Additional context
Add any other context or screenshots about the feature request here.

The baseDrawable.repeatCount is what I want, but it will be reassigned to options.parameters.repeatCount() ?: REPEAT_INFINITE, how should I play the repeatCount of baseDrawale automatically?

We should definitely support this. I don't think we can change the existing default behaviour unfortunately, but we could probably introduce a special constant that triggers this behaviour.

Thanks for your reply, I'm looking forward to your new version of coil to support this.

@colinrtwhite

how about defining a new chaining method in the ImageRequest Builder to solve this?

For example:

fun ImageRequest.applyRepeatCountFromData(): ImageRequest {
    val repeatCount = getRepeatCountFromMetadata(data) ?: return this

    return this.newBuilder()
        .repeatCount(repeatCount)
        .build()
}

Since the loop count in GIF metadata can be null, this method would attempt parsing when called. If parsing fails or returns a null value, the chaining wouldn’t proceed, and the default infinite loop would apply.

(Likewise for webp and heif)

It seems like fixing the decoder will take a lot of resources.

It seems like the solution to Image Request might be relatively simple.

What do you think?!?!?!
