Removing dependencies on beam-core and nest-eo classes and methods

nest-eo.GeoUtils methods:

 - refactored code to use jlinda, instead of nest conversion methods
 - introduced method wrappers for quick compatibility

beam-core.GeoPos() class:

 - moved GeoPos() from beam into jlinda, and refactored to doubles
 - clean-up and refactored-out leftover dependencies, SLCImage
Speed of Light in Constants and refactoring for it
Renamed GeoPos() to GeoPoint()

 - renaming to avoid ambiguous class declarations and conflicts
 - conflicts between: jlinda.core.GeoPos() beam-core.GeoPos()
 - GeoPos() still used in Topo Phase removal operator
 - also refactored methods and classes for this change
