Exa: Option to use some parts of the --long features

[simonsolnes]

As an example: Be able to list files with just sizes, nothing else.

My suggestion would be something like this:

exa -l --show-user=false --show-permissions=false

This would be great. I personally find the permissions column pretty unsightly, distracting, and only occasionally useful and would love a way to remove it.

PR #577 added options like --no-user and --no-permissions.
