Support for complex filler 'runes'?

[colecrouter]

Suggestion: Allowing Fillers to have assignable strings instead of runes. This would allow users to insert colour codes, complex shapes, and more.

Instead of having:

mpb.NewBarFiller("[=> |"),

we could do something like this:

mpb.NewBarFiller("[", "=", ">", "|"),

Well "complex runes" are supported, for example it's ok to pass string with emoji if that makes sense. Color codes can be added by means of decorators. I don't plan to change default bar filler, but don't mind having an alternative implementation.

PR is welcome!

I'm not sure I understand, could you give an example? I'd be more than happy to fork (as soon as I get a spare minute hahaha).

Following patch will make bar red.

Ah thank you, I see what you mean. I'll see what I can do.

@Mexican-Man Thanks for your contribution and idea.

I've implemented this feature in v7, see related example.
