Split out Trajectory & CircularArrayBuffer as independent packages

Ref: https://github.com/Vexatos/CircularArrays.jl

• Compare the speed between CircularCompatASARTSATrajectory and VectorCompactSARTSATrajectory. In th latest version their performance may be similar. If so, we can remove Circular* related data structures.

Good idea. I would be happy to help with creating CircularArrayBuffer.jl.

Cool, thanks. I need to do some benchmark tests first. I'll create a repo later and let you know.
