Adds aliases for eza or exa. Also change default blue colors to blue bold (file's date, modified flag in Git).

• ls lists directories first (applies to all aliases below).
• ll lists with long format and git status (applies to all aliases below).
• l lists all files.
• lr lists recursively as a tree.
• lx lists sorted by extension.
• lk lists sorted by largest file size last.
• lt lists sorted by newest modification time last.
• lc lists sorted by newest status change (ctime) last.

By default, this module will define the following ls alias:

alias ls='eza --group-directories-first'

You can override the default alias by defining one with your preferred options in your ~/.zshrc after the module is initialized. Example:

alias ls='eza --group-directories-first --icons'

This module must be sourced after the utility module, so this module can override the aliases set by that one.
