[blob] BlobDownloadOptions: rangeGetContentCrc64 and rangeGetContentMD5 cannot be set at same time.

### Which service(blob, file, queue, table) does this issue concern?
blob
### Which version of the Azurite was used?
3.3.0-preview
### Where do you get Azurite? (npm, DockerHub, NuGet, Visual Studio Code Extension)
npm
### What's the Node.js version?
v12.13.0
### What problem was encountered?
Unit test failure:
BlobClient.download all parameters set
Failed for
```
let exceptionCaught = false;
try {
await blobClient.download(2, 1, {
rangeGetContentMD5: true,
rangeGetContentCrc64: true
});
} catch (err) {
exceptionCaught = true;
}
assert.ok(exceptionCaught);
```

Here both `rangeGetContentMD5` and `rangeGetContentCrc64` is specified for the `BlobDownloadOptions` so we are expecting a failure.
Though azurite don't support Crc64 currently, it's up to the design whether to keep this behavior aligned.
