osl_maxfilter doesn't work with --trans default

[matsvanes]

The documentation of the osl_maxfilter notes we can use
osl_maxfilter input_files.txt /path/to/my/output/dir/ --trans default --origin 0 0 40 --frame head --force
to align head position between recordings by aligning them to a pre-specified position.
However, these options are currently not supported.
Having 4 flags is currently also not possible, so @AJQuinn suggestion was to create a new option that refers to
default --origin 0 0 40 --frame head --force

Should also include some documentation on the fact that this should be run separate to sss

@AJQuinn , @matsvanes

Does simply changing https://github.com/OHBA-analysis/osl/blob/main/osl/maxfilter/maxfilter.py#L453 to

stage3_args = {'autobad': None, 'force': True}

resolve this?

[cgohil8]

The above change will let you use -trans within the maxfilter command in OSL so i'm going to merge it in. This will close this issue. @matsvanes if the above change isn't the best approach for resolving this, re-open the issue.

I think your changes fixed part of it, but I don't think it enables you to specify a particular origin. Namely, the origin has three flags, where only 1 is supported. I do wonder whether this is already (partly) implemented by run_cbu_3stage_maxfilter (https://github.com/OHBA-analysis/osl/blob/main/osl/maxfilter/maxfilter.py#L463), where a fixed origin is specified?
