Pass nodata values to Encoder
This allows writing of geotiffs with non-default nodata values (e.g., -9999.0).
As of the time of this writing, only geotrellis-spark passes nodata values down,
everything else in core continues to use default nodata values defined by
geotrellis.
cleanup: move packages, delete unused files, etc.
Search for the geotrellis-spark jar instead of passing it down
add sparkMaster to CommandArguments
