Newer definition have been fetched from play-store-api. Moreover, the
following enhanchements are introduced:
- An new function utils.parseProtobufObj will automatically parse any
Protobuf object into a dictionary, so there's no need to manually
specify each field to parse
- Added toc() and acceptTos() functions
- Added deviceCheckinConsistencyToken and dfeCookie to API state and
headers
- Since search results are now divided into clusters, each one
representing a different subcategory, now the search() API call returns
a list of clusters, each one containing a list of apps
