defer binding initialization to point of use

[jonseymour]

Currently, the streams used in the .DIAGNOSTICS and .DATA object are the streams present at the point that the idiomatic-console module was initialized. It would probably be better to defer this initialization until the point of the rebind &/or the point of use since something, somewhere may have decided to patch process.stdout and process.stderr with alternatives.

Consider the best way to do this.
