Don't use rsync compression

[Dennis4b]

The current rsync archive command includes the "-z" flag, which enables compression.

This doesn't really save any bandwidth as mp4 video files do not compress well, however taxes the CPU of the Pi which is now the bottleneck in transferring.

Removing this flag doubles my transfer rates and no longer bottlenecks on CPU.

@Dennis4b Can you please indicate in detail what changes need to be made and to which file(s) in order to disable compression? Thank you.
