Allow overwriting of freeze files

[Azrael3000]

Currently tmuxp doesn't allow that, so it might be nice to support that.

I'm going to send you a few more issues with enhancements that I thought off. None of it is essential but it would improve the overall handling imho. I'm going to open each in a different issue so that it is easier for you to keep track of things.

I am going to associate this with #51, so the freezer can have tests against handling IO situations like this.

Currently, if you attempt to freeze and save the config to an existing file, then you are informed that you cannot do so, because the file already exists. I am willing to code and submit a pull request that would allow the tmuxp freeze command to overwrite the specified file.

Does anyone see any problems with this, because I did not look anywhere else in the code except the function responsible for the command?

Facing the same need here, it'd be great if tmuxp freeze could just overwrite an existing session.

I mean, yeah I could automate the deletion and then tmuxp freeze again, but that seems like an unnecessary workaround.

BTW, thanks for 'tmuxp'! It's the icing on the cake of my bash/vim/EmacsOrgmode/tmux workflow!

Cheers

Thanks for using tmuxp! It seems like tmuxp freeze --force solves this issue with the above mentioned PR.
