I wanted to try out the benchmarks but hit an error as it seemed there was an expected behaviour using require.resolve in node v10 that no longer works in v12+.

The benchmark, when run with node index.js was throwing this error for both uvu and tape:

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './bin.js' is not defined by "exports" in 
/Users/davidmosher/code/uvu/bench/node_modules/uvu/package.json

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './bin/tape' is not defined by "exports" in 
/Users/davidmosher/code/uvu/bench/node_modules/tape/package.json

This PR fixes that error by using absolute paths to ./node_modules, so that you don't have to rely on upstream test frameworks to expose their internals within package.exports, and updates the benchmark test framework dependencies, along with adding a benchmark for testdouble/teenytest.

Updated numbers I got running on Node 16 on a 2013 MBP w/ 16gb RAM:

~> "ava"       took   1.04s  (764 ms)
~> "jest"      took   1.63s  (333 ms)
~> "mocha"     took   269ms  (7   ms)
~> "tape"      took   138ms  ( n/a  )
~> "teenytest" took   133ms  ( n/a  )
~> "uvu"       took   96ms   (1.5 ms)

- node 12 and up start throwing ERR_PACKAGE_PATH_NOT_EXPORTED if the module includes an exports key that does not explicitly expose the imported path when accessed with require.resolve
- https://nodejs.org/docs/latest-v12.x/api/all.html#errors_err_package_path_not_exported
- this fix removes the require.resolve resolution in order to access the truly private executables for modules that dont all expose their internals in this way

I can confirm that bench/index.js doesn't fun for me on Node 18, but does run with the changes included here, so whether or not you want to add teenytest, the changes to bench/index.js seem like a good idea
