supporting multiple stripPrefix & replacePrefix entries via stripPrefixMulti

[SignpostMarv]

The environment that I'm tinkering in with sw-precache at the moment maps requests to public/foo.txt to public-precached/foo.txt while public/bar.txt is where it says it is;

Example config:

{
  "stripPrefix": ["www-root/public-precached/", "www-root/public/"],
  "replacePrefix": "public/",
}

/me has signed the CLA, but wondering why it doesn't use oauth for account association (using an email other than my google email address here)

CLAs look good, thanks!

Any ETA on this? See #141

As per #142 (comment), I think this can be closed without merging, correct?

I've implemented the method described in my comment on 142

Unfortunately, one test for the existing stripPrefix option are failing due to the changes in this PR, which makes me concerned that it's not backwards compatible.

Could you please ensure that the implementation addresses backwards compatibility, as confirmed by the test? Additionally, it would be much appreciated if you could add a new test along the same lines for the new option.

Using params.stripPrefix in params.stripPrefixMulti would be more concise.

Thanks, @SignpostMarv! 👍 from me, and this will be rolled into the upcoming 4.x release.
