Workspace Method yDoublingMeanFocus

Description

Focus in on y around some f_grid, then sets f_grid to
same focus

The algorithm will double the frequency spacing DF
steps away from F0, doubling it again DF steps away
from F0+DF, and so on until the end of the range.
The same happens but reversely towards F0-DF, ...

Inside these ranges, the values will be averaged
so that there's one value per original input
between F0-DF and F0+DF, 1 value per 2 original values
between F0+DF and F0+2*DF, and so on ever doubling the
number of original values per output value

F0 and DF are set inside the function to either the values
given by the user, or if they are non-positive as mean(f_grid)
and 10 * (f_grid[1] - f_grid[0]), respectively

Ignores NaNs and infinities in averaging calculations.
