Move log actions that work with String from co-log to co-log-core package

I would like to move the following functions to the Colog.Core.IO module:

They use only types from the base package so they won't introduce extra dependencies. But they are still useful. And they can be used as an example of very basic and default LogAction implementations. Also, later they can be used for testing with doctest

Hi,

It seems that MonadIO and Handle come from Relude which is not a dependency in co-log-core. Would you suggest adding it as a dependency with a Prelude module, like done for co-log?

Hi, @sphaso!

Relude just reexports MonadIO and Handle from the base backage. You can found them here:

1. MonadIO
2. Handle
