Move the stategy function into its own file

[philipwalton]

This PR:

• Moves the strategy() function form _default.mjs into it's own file, so it can be imported on it's own (e.g. import {strategy} from 'workbox-streams/strategy.mjs').
• Removes the _default.mjs file as there's no "special" default export outside of what's already in _public.mjs.

Coverage decreased (-0.003%) to 86.117% when pulling be84ed2 on streams-structure into 6c054a7 on master.

Some additional notes: this is actually even harder to use than I'd originally thought. At the moment if you want to use strategy via import, you have to pull in the entire module since named exports aren't used (only the default), and you have to reference the private _default.mjs file.

In other words, you can't do this:

import {strategy} from 'workbox-streams';

Or this (my preferred approach):

import {strategy} from 'workbox-streams/strategy.mjs';

You have to do this:

import streams from 'workbox-streams/_default.mjs';

// Then use `strategy` as a property fo the `streams` default export...

(Sorry for not catching this in my review of streams package...)

👍

A lot of the JS module exports are a black box to me, so if you think there are other packages that need remediation (and it's backwards-compatible), go for it.
