[Feature] Add properties to track bytes compressed/decompressed to CompressionStream/DecompressionStream

[bill-poole]

It is sometime useful to know the number of bytes compressed by a CompressionStream and decompressed by a DecompressionStream. There is currently no easy way to determine this. Therefore, it would be great if properties were to be added to the CompressionStream and DecompressionStream classes that count the number of bytes compressed/decompressed.
