[Feature] Global parameter to output result of command as JSON

[o-l-a-v]

Would be great with a global parameter to output results of a fnm command as JSON, to make it easier to parse the information from other tools, like PowerShell in my case.

I want to automate updating nodejs LTS version fnm install --lts, set new version as default fnm default <new_version>, uninstall older version fnm uninstall <old-version>. It'd be much easier if I could parse the output of all these commands as JSON.
