POC: tape + power-assert = ???

[tape](https://github.com/substack/tape) is self-excutable test library.

We want to mix tape assert and [power-assert](https://github.com/power-assert-js/power-assert).
## Recipe
- set [power-assert-js/espower](https://github.com/power-assert-js/espower)'s [options.patterns](https://github.com/power-assert-js/espower) that match tape asset.
- How to set this config to [various](https://github.com/power-assert-js/espowerify) [power-assert modules](https://github.com/power-assert-js/espower-babel) at one time?
- extends `tape.Test.prototype` https://github.com/azu/tape-power-assert/blob/5390499b04e6adffb39148d51dceb3a628a27651/test.js#L5-L6
- apply [power-assert-formatter](https://github.com/power-assert-js/power-assert-formatter) to tape output.
- How to convert output object to TAP?

Start by reading the extension of tape.Test.prototype in test.js at the referenced commit, then review the espower options.patterns and the power-assert-formatter integration described in the recipe. Determine how the power-assert modules should be configured together and how the formatter's output can become TAP; done means the POC produces useful power-assert diagnostics through tape's TAP output.
