feat: Allow users to specify a maximum length for files/folders

[BrendanMesters]

Requested behaviour

I think a specific option, which could limit the name length displayed when using eza would be usefull.
This way your view would not be limited to one collumn by a single file with a long file name.

How would this look

You could add another option to eza, e.g. --max_length and set it to a value.

if you have a folder containing a file "foo_bar_baz.txt" for example, but you only want at most 8 characters to be dislpayed per file you could simply call

$ eza --max_length 8
> foo_bar_

Why is this necessary

Its not a high priority feature, but it would be very nice to set a reasonable limit (40 or 50 characters say), as I find that specifically the Downloads folder can sometimes be infested by random files with to long a name. This can also be a problem when saving papers under the full title.
