Add count of floored T2* values in logging

[dowdlelt]

Summary

Related to #585
We now have _apply_t2s_floor, which fixes divide by zero issues related to very low t2* estimates. It may be useful to have the option to record the number of voxels corrected with this, perhaps when asking for verbosity. I don't see any obvious dangers of the correction, but currently it is invisible.

Next Steps

• count the number of voxels that have "bad" values
• report this value if verbosity is requested.

Thanks for opening this issue @dowdlelt !
I agree that this would be good because if it happens a lot, it could be an early warning that something has gone wrong.
