Creates the compressed bzip2 archive.
async bzip2.compress(): Promise<void>
Invoking Compress creates the archive specified by ArchiveFile. When the method is called, the file specified by FileDecompressedName will be opened, and the file specified by ArchiveFile will contain the compressed output.
As the data is compressed the Progress event will be fired at regular intervals. This event may be used to stream out the bzip2 file, or to display a progress bar to the user.
