Upgrade dependencies, bump to 1.7.0.

Upgrade the following depedencies:

* Hadoop from `2.7.3` to `2.7.4`.
* Spark from `2.1.0` to `2.1.2`.
* Circe from `0.7.0` to `0.8.0`.
* Scalaz from `7.2.9` to `7.2.16`.
* SLF4J and adapter libs from `1.7.24` to `1.7.25`.

These should be non-breaking changes for you with the exception of
Circe, which is why we have bumped the major version to `1.7.0`.

 **Spark connectors**:

-"com.intenthq.pucket" %% "pucket-mapreduce" % "1.6.0"
+"com.intenthq.pucket" %% "pucket-mapreduce" % "1.7.0"
 ```
 
 These dependencies should be combined depending on your usages; for example if you use Thrift and Spark then use the following:
 
 ```
-"com.intenthq.pucket" %% "pucket-thrift" % "1.6.0"
-"com.intenthq.pucket" %% "pucket-spark" % "1.6.0"
+"com.intenthq.pucket" %% "pucket-thrift" % "1.7.0"
+"com.intenthq.pucket" %% "pucket-spark" % "1.7.0"
 ```
