implement as transform

[fcurella]

I took the original code and implemented it as browserify transform. This way we don't need to write temporary files to disk and we can leverage @cypress/browserify-preprocessor's handling of watchers and reloading. (ref #1)

I've also made the preprocessor accept options to be passed down to browserify.

Note: I've used the airbnb style simply because that's what I usually have set up. If you prefer a different style, let me know and I'll make the changes (maybe add an .eslintrc to the repo?)

do you have something against using (options = browserify.defaultOptions) here instead? I think this way we could keep the backward compatibility and make it as easy to set up as it already was (and if someone wants to customise - there is a way).
Otherwise - great work :) this makes this plugin really usable :) and we are still just at the beginning of the journey

Good idea, I'll make the change

I have a question about this. My understanding is that @cypress/browserify-preprocessor already takes care of watching. When trying to re-implement this, I tried omitting watching completely and I am observing identical behavior with my fork. Thus, why is chokidar necessary here?

Are your tests restarting when either .feature file or your step definitions change? Or only when your .feature file changes? I think that was the point here. Maybe it's started behaving differently comparing to 2018?

Both!

I thought that could be it, but they had watchify in v1.02 as well, seen here.
