Replace comma-separation in --manacc with space-separation

[tsalo]

Summary

In most cases where we allow multiple inputs for a given argument (e.g., -d, -e, and --gscontrol), tedana accepts a space-separated list at the command line. This should simplify how manacc is handled internally, since the tools already exist to parse nargs='+', and I feel like space-separated parameters are more intuitive at the command line.

Next Steps

1. Set nargs for --manacc to '+'.
2. Set type for --manacc to int.
3. Remove string parsing for manacc within tedana_workflow.
4. Update documentation.
5. Update any tests that use manacc.
