advance_wdrifty_explicit subroutine calculates and adds the y-component of the magnetic drift term to the RHS of the GK equation
start the timing of the y component of the magnetic drift advance
calculate dg/dy in (ky,kx) space calculate dbpar/dy in (ky,kx) space
assume only a single flux surface simulated transform dg/dy from k-space to y-space add vM . grad y dg/dy term to equation
calculate dphi/dy in (ky,kx) space Here g_scratch is
in k-space that has been pre-calculated and stored
transform d
Note that this is here because for FFS te gyro-average is calculated once outside this routine TODO-GA: can we do something similar for fluxtube to save cpu time? calculate dphi/dy in (ky,kx) space
stop the timing of the y component of the magnetic drift advance
