Release 5.1.0

Version 5.1.0 brings some minor improvements and changes

_What's new?_

• Added msngr.parallel() and msngr.series(). These are handy for asynchronous patterns and already existed, internally, to msngr.js. This simply exposes them but in a more simplified way.

_Misc changes_

• msngr.is(Promise) should now work in cases where Promise is pollyfilled.
• Fixed issue in mache where calling .data property would set a transaction to the baseline dataset
