Clean-up of WarpOp

Removed nested class for InSAR interpolation LUTs, and refactored to generic class for 'LUTs for InSAR resampling' coming from jLinda.

Notes:
* In process of refactoring few small bugs being fixed - nothing major - inconsistencies in interpolator tags.
* Dependency on just packaged and depolyed jLinda v0.7-SNAPSHOT
* No direct dependency of jblas anymore, perhaps coregistration pom can be cleaned-up as well?
