error 400 caused by continuation-token and start-after

[mervynzhang]

Hi @gaul ,

delta-kernel-rs report 400 when list more than 1000 files because of this check:

s3proxy/src/main/java/org/gaul/s3proxy/S3ProxyHandler.java

Lines 1389 to 1391 in 4976e17

	if (continuationToken != null && startAfter != null) {
	throw new S3Exception(S3ErrorCode.INVALID_ARGUMENT);
	}

In some case, continuation-token and start-after would be both set, but it's not something really bad. I tried to submit a PR to delta-kernel-rs to avoid this error, delta-incubator/delta-kernel-rs#312.

It will be helpful if we can loose this check too. Is it Ok to just log a warning or just skip this check?
