Version 3.0alpha1 - 12/20/24 First alpha of rapidtide 3.0

• (rapidtide) The --fixdelay option has been split into two options. --initialdelay DELAY lets you specify either a float that sets the starting delay for every voxel to that value, or a 3D file specifying the initial delay for each voxel. --nodelayfit determines whether the delay can be adjusted from its initial value. Closes #171. KNOWN ISSUE: If you supply an initial delay map, instead of using the global mean, you should use the delays to make your first stage regressor. Currently that is not the case.
• (rapidtide) Reorganized command line options and adjusted the default values.
• (rapidtide) Help output now shows the filter ranges.
• (rapidtide, retroglm) Added delay refinement using the ratio of the fit coefficients of the regressor and its time derivative.
• (rapidtide, retroglm) Fixed a bad shared memory leak.
• (retroglm) Significantly enhanced logging.
• (retroglm) Added canary files.
• (rapidtide) Implemented delay map patching.
• (rapidtide) Write out individual EV timecourses.
• (Docker) Cleaned up some internal variables.
• (Docker) Improved build and testing scripts.
• (io) Added function to compare nifti files with some tolerance.
• (docs) Automated more table generation.
• (package) Merged some dependabot PRs.
• (package) Fixed a fairly big, but not necessarily impactful bug. mlregress returned R2, not R, so anything referring to the R of a fit was actually squared (R was actually R2, R2 was actually R4).
