v4.0.0

For full set of changes see #45

breaking changes

• change to the options args passed into the library. now simplified to an object rather than trying to support positional parameters
• default API and download user agent has been replaced with those from a Nexus 5X device. Please note that you can override the user agents via the options object as mentioned in the README
• added info to README about getting user agents and device id to override via the new options object
• the default device profile has also been changed for travis builds to reflect the new device profile.

breaking field changes

By using a newer device model some of the fields have changed (and some previously unpopulated fields are now populated).

• see 4.x breaking changes for an updated list.

e.g.,

• details.appDetails.numDownloads field now returns something like "100,000+ downloads" -- this is an upstream change from google.
• details.appDetails.certificateHash - now returning an empty array as it is deprecated by details.appDetails.certificateSet which returns an array of objects with certificateHash field set.

new features

• support for downloading additional files API thanks to @CommonRaven

dev changes

• will now use semistandard to lint the code before tests... hopefully encourage a little cleaner code throughout
• so far I've given up the refactor branch in favor of incremental changes to master... babel was just too annoying to work with to get the benefit of async and await
• switched over from tape to tap for tests... not sure why but I liked the different report options from tap incase we decide to change things up
