Added fingerprint tool for computing a "fingerprint" (a hash) for directories and files in order to assess if any content has changed.

Added --version option to both replay and dispatch tools.
No other changes

replay 1.0 release.
First public binary release after many months of development.
The package installs both tools in:
/usr/local/bin/replay
/usr/local/bin/dispatch
The executables are "fat": x86_64 for classic Intel Macs and arm64 for Apple Silicon Macs - tested and running very fast on M1 machines.
Codesigned and notarized for installation outside of App Store.

A lot of usage examples are in the replay's repo "test" directory (not installed by the package)
If you download the code or clone the repo locally you can ensure all works as expected by running all tests:
cd /path/to/git/replay/test
./test.sh /usr/local/bin/replay
./dispatch_test.sh /usr/local/bin/replay
(other longer tests can be done the same way)
