Add log format parameter: {padding-level}

[yeondudad]

for fixed width

[katzgrau]

level-padding param is officially in release 1.2.0

[yeondudad]

it's not same. {padding-level} is level with left-padding.

[katzgrau]

But can't you achieve the same with level-padding?

$logFormat = "[{date}] [{level-padding}{level}] {message}";
