log file config need a path and file name template as different values

[clint-lawrence]

Relevant code is in src/fixate/config/init.py. I think it would make sense to split tpl_csv_path into two components. One which is the folder location and then the file name.

Although the current implementation may be fine with some documentation and example on what to specify for absolute vs relative paths.

One way to think of it is, "use the default log file name, but put it in this folder". the current implementation will always use the cwd with the default template, and if you override, you need to override the name/timestamp portion. not just the folder path.
