Fix up scripts and dependencies and things (#15)

* Fix merge conflict markers in react bundle

* Set fps-emit back to `src`, `lib` doesn't exist

* Install some missing dependencies

* Update README instructions for fps-emit

* Update all package-lock.json files

Due to https://npm.community/t/754 these had to be rebuilt to get the
file:../../fps-emit package install to work

* Update benchmark versions to latest v5 and v6

* Switch from NPM to Yarn

* Use weighted average FPS

* Fix up README

 # react-redux-benchmarks
 Performance benchmark harness for React-Redux
 
+This repo expects that you are using Yarn for package management.
+
 # Running benchmarks
 ```bash
-npm run initialize
-npm start
+yarn initialize
+yarn start
 ```
 
 After benchmarks have been initialized, you can run with simply:
 
 ```bash
-npm start
+yarn start
 ```
 
 ## Running specific versions
 
 To specify a single version:
 
 ```bash
-REDUX=5.0.7 npm start
+REDUX=5.0.7 yarn start
 ```
 
 To specify running against multiple versions:
 
 ```bash
-REDUX=5.0.7:4.4.9 npm start
+REDUX=5.0.7:4.4.9 yarn start
 ```
 
 To run a specific benchmark:
 
 ```bash
-BENCHMARKS=stockticker npm start
+BENCHMARKS=stockticker yarn start
 ```
 
 or specific benchmarks:
 
 ```bash
-BENCHMARKS=stockticker:another npm start
+BENCHMARKS=stockticker:another yarn start
 ```
 
 ## Setting run length
 
 By default, benchmarks run for 30 seconds. To change this, use
 
 ```bash
-SECONDS=10 npm start
+SECONDS=10 yarn start
 ```
