redo ExtractROI

[yibeichan]

Hi @djarecka , I redid extractroi by changing the output basename from _trim to _roi. (passed pytest locally)
(just a note from today's discussion) @effigies mentioned that we can set requirements for argstr that for each of x_min, x_size, y_min, y_size, z_min, z_size requires [x_min, x_size, y_min, y_size, z_min, z_size], then for t_min, t_size, requires [t_min, t_size]. We can manually do this.
our current converter has something called input_drops link, of which the usage can be found here. So it inherits the crop_list from nipype
let me know what we want to do with extractroi further.

we can talk more tomorrow, but I think input_drops works as intended here, right?

[yibeichan]

yes, input_drops generates the same list as the one in nipype see here. but in the morning, we were talking about x_min, x_size, require y_min, y_size, z_min, z_size; t_min & t_size require each other. this sort of requirement is not in our current extractroi, if we want it, we have to manually define it.

this should be finished after the issues is resolved: #49
