Some logging improvements

[36000]

Some simple fixes:
Label tqdm bars;
print before doing SYN fitting that that is what you are doing
print before doing CSD fitting that that is what you are doing

Have an option for the CLI to print output to a file. In this case, make sure the TQDM bars do not take up a bunch of lines

When using pyAFQ through the Python API (e.g. with ParticipantAFQ.export_all()), how do we get log to file?

[36000]

You can redirect stdout and/or stderr to a log file. One of these solutions could work:

Should probably consider tqdm mininterval with various values for streaming vs logging. Currently log files can be MB because tqdm is printing a whole new line way too often (see picture below for example). A logger probably needs an updated every minute or so?

Include in #920?

Yeah - this is really annoying. Here's another potential approach: https://stackoverflow.com/a/75059930

And yes, could you please add one of these approaches to #920? That would be great.
