Add 'indent' parameter to 'put' command

[cavus700]

I would like to add a new command line parameter for the put-command to set the indention level for various outputs. The different parsers are already respecting the IndentOption but it is not possible to pass it via the cli.

Thanks for the contribution @cavus700.

Before merging I'd like to add support for the indent flag across all commands for consistency, along with the related tests.

You're welcome to do this, but if not I expect I'll get to it in the next couple of days.

I've added the option across the commands but would like to add some tests next.

Thank you for extending the PR :)

Sure this feature is not time critical for me but I thought it would be a nice extension. Do you need some help with the tests?

[TomWright]

I'll take all the help I can get. I'm juggling a lot at the moment

Thanks for adding those tests @cavus700 that's great. Lets get this merged!

Thanks for the contribution 👍
