Add option to control t2smap fittype #3029
Description
What would you like to see added in fMRIPrep?
Users have reported memory issues with the nonlinear T2*/S0 fitting setting (e.g., #2935 and #2827), so it might be worthwhile to give them control over the setting. I don't think it merits a command-line parameter, but is it perhaps something that could be controlled via the config file?
Do you have any interest in helping implement the feature?
Yes

Alternatively, I could change the fittype from nonlinear to the less memory-intensive, but potentially less accurate, loglin option.
