Add newest ard-reset-arduino flag support.

[JDuchniewicz]

The option --zero no longer works with Arduino 1.8.13 for SAMD boards and has to be replaced with the --caterina option.

Please can you add some more context to ‘no longer works’?

I’m still using —zero with the Arduino SAMD bootloader with no issue.

The ard-reset-arduino does not have the --zero option anymore in my case (1.6.0 version of the program).

[tuna-f1sh]

The --zero option was added with the SAMD support - not removed.

The release version of this repository (1.6.0) does not include support for SAMD. You need install ard-reset-arduino from the master/HEAD and not use a package manager.

Hmm this is embarrassing. I thought that the upstream changes removed that option... Closing it in this case 😄
