Use hadoop-lzo 0.4.20 from Snowplow Bintray maven

Otherwise

[error] (update) sbt.librarymanagement.ResolveException: unresolved dependency: com.hadoop.gplcompression#hadoop-lzo;0.4.20: not found

Add org.apache.commons.collections dependency otherwise when bumping Scala version and all the libs it is failing with:

It seems that so far we've been lucky enough that this class was in the classpath, but with the bump of all the libraries it's not any more.
