Support for Spark 2.4.3

[mscnop]

Hi, this is my first ever PR to anything, so please bear with me if I have done something terribly illegal/bad practice :)

I have updated a range of the dependencies to allow for Magellan compatibility with Spark 2.4.3 and Scala 2.11.12. In order to make it work with the new versions of the dependencies I had to change a few things regarding class/object creation.

All tests are passing, when I run "sbt test".

I was able to get this working with https://github.com/mscno/magellan for spark2.4 .

Does this preserve backward compatibility with Spark 2.3?

I just tested it out for spark2.1 and it doesn't work for it.

Hi,

When i did the changes, I was able to make it work for both Spark 2.3.x and Spark 2.4.x. And both versions compile and test without errors in the CI travis builds: CI Results.
I was not able to maintain backwards compatability with SPark 2.1.x or Spark 2.2.x. /Mads
