Change multi-file approach to use action for each word

[MichaelCurrin]

e.g. Create foo, update bar and delete bazz

[MichaelCurrin]

Currently it does this:

Various changes to baz.txt, bar.js and README.md

This is much easier to do now that #38 is mostly done.

This issue is also very similar to #52, which will handle many files e.g. update foo.txt and delete 6 files

The intention of this issue is to handle just a few files. e.g. update foo.txt and delete bar.js

This currently isn't nice for only 2 files with different actions

build(deps): create 1 file and update 1 file

This should be

build(deps): update package.json and create package-lock.json
