When deploying ML models, one option is to archive andcompress the model artifacts into a tar.gz format.
Although this method works well for small models,
compressing a large model artifact with hundreds of billions of parameters and
then decompressing it on an endpoint can take a significant amount of time.
For large model inference, we recommend that you deploy uncompressed ML model.

If you want to use uncompressed ML model,
you can provide options to `ModelData.fromBucket` like a following the code.

```typescript
import * as s3 from 'aws-cdk-lib/aws-s3';

const bucket = new s3.Bucket(this, 'MyBucket');
const modelData = ModelData.fromBucket(bucket, 'path/to/artifact', {

The CompressionType and S3DataType enums seem to be used a lot in conjunction with each other, and when their behaviour changes this drastically between combinations, it makes me wonder if there is any way we can combine the two? Right now, for instance, there doesn't seem to be anything documented about what will happen if I combine CompressionType.GZIP and S3DataType.S3_PREFIX, if that's a valid combination.

* - If you choose `S3DataType.S3_OBJECT` as the value of `s3DataType`, then SageMaker will split the key of the S3 object referenced by S3 URI by slash (/),
* and use the last part as the filename of the file holding the content of the S3 object.
* - If you choose `S3DataType.S3_PREFIX` as the value of `s3DataType`, then for each S3 object under the key name pefix referenced by S3 URI,
* SageMaker will trim its key by the prefix, and use the remainder as the path (relative to `/opt/ml/model`) of the file holding the content of the S3 object.
* SageMaker will split the remainder by slash (/), using intermediate parts as directory names and the last part as filename of the file holding the content of the S3 object.
* - Do not use any of the following as file names or directory names:
* - An empty or blank string
* - A string which contains null bytes
* - A string longer than 255 bytes
* - A single dot (.)
* - A double dot (..)
* - Ambiguous file names will result in model deployment failure.
* For example, if your uncompressed ML model consists of two S3 objects `s3://mybucket/model/weights` and `s3://mybucket/model/weights/part1`
* and you specify `s3://mybucket/model/` as the value of S3 URI and `S3DataType.S3_PREFIX` as the value of `s3DataType`,
* then it will result in name clash between `/opt/ml/model/weights` (a regular file) and `/opt/ml/model/weights/` (a directory).

This docstring feels unnecessarily lengthy, and the mention of what file/directory names doesn't seem relevant, at least for the enum. Is there anyway we can add a @see tag and link to the documentation instead for all this extra information?

Reading this, I interpret it as telling the user to use the ModelDataUrl or ModelDataSource properties, but looking through the rest of the changes, it seems like this is something handled internally. Is there a reason the user needs to know about what's going on under the hood?
