Ignoring whole packages, better output distinction

[finwe]

• bug fix? no

• new feature? yes

• BC break? maybe?

• The ignoring fourliner makes easier to ignore a whole package with assets in root (see this SO QA)

• The output prefixes makes distinction of the origin output clearer

IMHO package can be ignored this way

{
    "extra": {
        "cleaner-ignore": {
            "slevomat/eet-client": ['']
        }
    }
}

Seems right, not very intuitive, though. Should I remove the ignoring with * and just update the readme?

[finwe]

I guess the most intuitive would be something like this

{
    "extra": {
        "cleaner-ignore": {
            "slevomat/eet-client": true
        }
    }
}

but would mean a larger impact on the code.

I added full support for wildcards here b17b6992783f13275119b766d7ce35ba002144c6 and your first commit.
