logger: add optional format arguments to default_logger

default_logger function accepts optional arguments for the format of the console and file loggers

For example for readable indentation with longer function names (e.g. with FSI or ROUKF, 30 chars instead of 8):

loglevel = "DEBUG"
fmt_console = (
    f"<lvl>{{level:<{len(loglevel)}}}</> | "
    "<c>{extra[classname]:<30}:{function:<30}</> - <lvl>{message}</>"
)
fmt_file = (
    f"{{time:YYYY-MM-DDTHH:mm:ss.SSS}} ({{elapsed}}) | {{level:<{len(loglevel)}}} | "
    "{extra[classname]:<30}:{function:<30} - {message}"
)


...

# something like:
    default_logger(
        Path(options_fsi["io"]["write_path"]).joinpath("run.log"),
        level=loglevel,
        fmt_console=fmt_console,
        fmt_file=fmt_file,
    )
