(PureBasic) SFTP Upload with Bandwidth Throttling

Demonstrates how to upload a file to an SSH server in the simplest way with bandwidth throttling. Bandwidth throttling for all SFTP communications can be achieved by simply setting the BandwidthThrottleUp or BandwidthThrottleDown properties. (One limits the transfer rate for uploads, the other for downloads.)
