Currently limited to only cloning whole disks, not select partitions.
We need to specify the --size due to a bug under macOS; it fails to
detect the size of the device/partition and reports 8192 PiB instead.
Before starting a recovery run verify the source and destination have
not changed. This will prevent issues on some extreme edge cases but
the main goal is for disappearing source drives with heavy damage.
e.g. A very damaged source drive disappears mid-recovery, drops off and
before would need a restart, or unplug/replug, to continue. Now we can
attempt to re-detect the drive and resume recovery without leaving the
script. If for some reason the drive order were to change then we'll
avoid using the wrong source or destination device.
If tmux wasn't already running it would output an error but still work.
The new approach will suppress that since we're not concerned if it's
already running or not, just whether the desired session is.
Modified the live macOS args to support connecting to the HW-Diags
session remotely (more easily at least).
Not sure where the old reference to an "other" timezone came from.
Going to use the POSIX style esp. after finding the answer below.
Thankfully both options appear in macOS 10.11-10.15 in my testing.

This was not being pushed from a testing MacBook so I'm adding it all
at once. This is unfinished, still needs scripts to prep the working
macOS env from which the live env is built.
El Capitan code is likely to be dropped completely. Installing or
compiling dependencies in brew is problematic at this point.
