Add the ability to parse multiple shells or specify prefered shell

[licentiapoetica]

I really like the idea of this tool but in my case I switched mid year to zsh from bash and therefore I only have a limited set of statistics, it would be great if there would be the option to either specify a history file via arg that is being read or maybe parse all available histories and combine them.

thanks for the cool tool

Thanks for your suggestion! It makes sense to provide an option for specifying multi history files.

In the meantime, you can trick the program with 'SHELL=/usr/bin/bash ./cmd-wrapped'. :)

The tool doesn't work if my history file is not at the default location. It'd be great to be able to specify the history file location
