Allow for an option to pass a command as an option when invoking hx

[andydoan]

I may very well have missed this functionality when skimming the docs and repo, please let me know if I did! I am essentially looking for the equivalent of vim's -c and --cmd options.

       -c {command}
                   {command} will be executed after the first file has been read.  {command} is interpreted as an Ex 
                   command. If the {command} contains spaces it must be enclosed in double quotes (this depends 
                   on the shell that is used). Example: Vim "+set si" main.c

                   Note: You can use up to 10 "+" or "-c" commands.

       ...

       --cmd {command}
                   Like using "-c", but the command is executed just before processing any vimrc file.  You can use 
                   up to 10 of these commands, independently from "-c" commands.

Is this behaviour currently possible or being considered at all?

Cheers!
