UserAgent Parser does not support patchMinor

[lukezhang2000]

patchMinor is not included in the UserAgent Parser. For Chrome browsers, the parser will not catch the full name of the UserAgent, i.e. (https://github.com/ua-parser/uap-core/blob/09e9ccca9fcfc4348ae9e89815135bafcd0676bb/tests/test_ua.yaml#L2579-L2584)
For 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.78 Safari/537.36', the patchMinor would be "78", but that would not be captured by our parser.

Is the exclusion of patchMinor intentional for the UserAgent browser, or should that be added into the UserAgent class?

I believe there is an ongoing PR that's been out for this: #61
