Add the "EtagToNotMatch" parameter to "Read-S3Object" cmdlet

[thedevopsmachine]

The -ETagToNotMatch parameter exists on the Get-S3ObjectMetadata Cmdlet, but it's not much use there. By adding it to Read-S3Object, I can specify a MD5 hash of a local file, and if the local MD5 matches the remote file MD5, it doesn't need to download the file. This can eliminate the need for me to make 2 API calls (i.e. Get-S3ObjectMetadata and then Read-S3Object).

Expected Behavior
Read-S3Object should have a ETagToNotMatch parameter

Current Behavior
Read-S3Object does not have a ETagToNotMatch parameter

Possible Solution
Add the ETagToNotMatch parameter to Read-S3Object Cmdlet

Is is worth noting that Read-S3Object uses the TransferUtility, so this requires more investigation and likely a change in the .NET SDK.
