* partial parsechunk implementation * fix format * param name fix * rename functions * match MxStreamController::RemoveSubscriber * implement rest of MxDSBuffer * Fixes and better matches * Matche ParseChunk 100% * Match MxDiskStreamProvider::VTable0x20 * Match MxDSBuffer::CalcBytesRemaining * Minor stuff * Minor improvements * Refactor functions --------- Co-authored-by: Christian Semmler <mail@csemmler.com>
