Also validate args for clojure tools usage

[lread]

Switched from clojure.tools/cli to org.babashka/cli for command line
parsing.

Usage help is now shown on request, via --help for -M usage
or :help true for -T and -X tool usage, and on usage error.

Usage help shows appropriate option syntax for -M vs -T usage.

Help is also shown on usage error.

Now emit a warning on deprecated option usage (currently only --no-diff
is deprecated).

I did not realize all multi value args support : separator syntax.
Updated README accordingly.

Cli tests updated accordingly and I brought in nubank's matcher
combinators to make comparisons easy to write and error diffs easy to read.

After I tackle #274, I'll incorporate these checks for lein plugin usage.

Closes #280

Hi @liquidz when you find some time, looking forward to learning what you think.

With babashka cli, it is relatively easy to add usage help, so did that.

-M usage:

$ clojure -M -m antq.core --help

Hi @liquidz, I expect you are busy with life and other things.
Let me know what you think after you've had a chance to take a peek.

Hi @liquidz! I am still happy to bring this one to completion, if you find some time/interest.
