Logger pretty newlines

[RiskoZS]

This pull request adds a new boolean client option prettyNewlines (true by default) and a new Logger option + mutators which, when true, makes the logger pad newlines so that they align with the timestamp label. This is just a cosmetic change to make logging multi-line strings neater.

As an example, what before was:

2021-10-23 15:31:25 | [INFO]     | Hi!
This is a
multiline string!

now becomes:

2021-10-23 15:31:25 | [INFO]     | Hi!
                                 | This is a
                                 | multiline string!

Can you show where you get 16 from? We probably shouldn't hardcode this if it can be dynamically generated (maybe as a module local value).

The label (line[3]) is always length 10. The two separators (|) (line[2] and line[4]) are both 3, so 6 total.

Can you make this happen?
