Detailed Description

Write-through buffer using heap storage and owned stream pointer.

Example usage:

 auto stream = std::make_unique<FileStream>("file.txt", File::ReadWrite);
 auto bufferedStream = new DynamicPrintBuffer(std::move(stream), 512);

 // write to bufferedStream as required via callbacks, etc.
 ...

 // This destroys both buffer *and* the file stream
 delete bufferedStream;
