Override active profile using a flag

[fenhl]

The Problem

I'm writing a script that calls ferium and portablemc in order to automatically sync the Minecraft version to my server's, then update Fabric and mods before launching the game and connecting to the server. Ideally I would like to do so without modifying the active ferium profile. Currently, the only way to do this I can think of is:

1. Parse the output of ferium profile to remember the previously active profile
2. Use ferium profile switch to switch to the profile for playing on the server
3. Run ferium profile configure --game-version to ensure the Minecraft version is correct
4. Run ferium upgrade to ensure mods are up to date
5. Run ferium profile switch to restore the previously active profile

Your Solution(s)

It would be nice to have a --profile option that overrides the active profile for the scope of this command only. This would allow the workflow above to be reduced to:

1. ferium --profile=foo profile configure --game-version
2. ferium --profile=foo upgrade

There is a related issue #163, but that has a much wider scope than this one. This is technically a duplicate of that, but since this feature is much easier to implement, I'll leave this open and prioritise this.

Also thank you for pointing out portablemc! I've always wanted a CLI Minecraft launcher, it seems like my dream come true. Plus it's being rewritten in Rust!!
