AWS 2-2: Use New mmw-geoprocessing in Worker VM

[rajadain]

Once a new, upgraded mmw-geoprocessing is available, post WikiWatershed/mmw-geoprocessing#106, import it to the Worker VM, performing appropriate upgrades (dependencies such as Java, Scala, etc).

Doesn't look like any Java upgrades are needed.

I am getting this message when using the 6.0.0 version:

Exception: [convert_data] huc8__1748 Geoprocessing Error.
Details: The request content was malformed:
EntityStreamSizeException: incoming entity size (8426814) exceeded size limit (8388608 bytes)! This may have been a parser limit (set via `akka.http.[server|client].parsing.max-content-length`), a decoder limit (set via `akka.http.routing.decode-max-size`), or a custom limit set with `withSizeLimit`.

This is even after setting MMW_GEOPROCESSING_MAXLEN to 150m. Will investigate further ...
