Transform to 6 to 4 and 3D coordinates

[JoseRuedaRueda]

General description

Several diagnostics such as FILD or INPA have as natural starting point the 6D information of the measured particles (X, V), it would be ideal to have a function to calculate the GC variables from them

Detailed request

Implement the first order transformation explained here: https://ascot4fusion.github.io/ascot5/physics.html#gyro-orbit-a-k-a-particle
