Remove Guava dependency

LeoNiedermeier commented 2 years ago

Is your feature request related to a problem? Please describe.

The library includes guava, but uses just two classes (so far I can see)

Both can be replaced with plain java classes, e.g

Describe the solution you'd like

No guava dependency because

you use just few classes from guava which can replcaed by core java classes
version conflicts, because other dependencies in a application which uses snowplow can also include guava with different version
as user of this library i do not want additional transitive dependencies in my application

Describe alternatives you've considered
