Add picture max_size options to reduce memory usage

### Requested feature

There're some PDFs (maybe scanning copy) contains large pictures holds cost lots of memory.
So I'm try to find a way to scaling page picture.

### Alternatives

I have two ideas:

1. The `Page.get_image` have a `max_size` param, so just set it with options.

2. There's only `PdfPipelineOptions.images_scale` for generating a extra scaled picture in `PagePreprocessingModel`, so just let the `image_scale` be the default page picture scale, and all other models using it.
