feat(fixes): shebangs and cmd-line standards

[ocehugo]

Just small annoying bits - missing shebangs and non-standard cmd line arguments lines. @mhidas, worth checking if this is safe since I didn't check how you handle the calls to these tools .

Note that this changes many of the command-line arguments

• The required parameters have become positional args.
• Some of the optional ones have been renamed to match corresponding variable/arg names within the code.
• Some single-letter alternatives have been added.

This brings the interface more in line with standard command-line tools (on Linux).

@alexgleith Why did you close this? I still think it's relevant, though not high priority for us as we run this code with a Python process, not from a shell. However, as this is an open-source repo (I know at least one group at UNSW using it), the command-line functionality is there and this changes it in a non-backwards-compatible way, I'm saving this until we're ready to release a v2 (see https://github.com/aodn/python-aodntools/milestones)

I closed it because it hadn't been touched for over a year. Sorry :-)
