feat: Add reset_stats method to LineProfiler for resetting accumulated profiling data

[hidva]

This PR introduces a new method reset_stats() to the LineProfiler class, allowing users to reset internal profiling statistics without recreating the profiler instance. Use Case:

start_ts = time.monotonic()
self._line_prof.enable()
# logic 
self._line_prof.disable()
end_ts = time.monotonic()
self_prepare_us = (end_ts - start_ts) * 1e6
if self_prepare_us >= 3 * 1000:  # 3ms
    profstat = self._line_prof.get_stats()
    logger.info(
        "dur_us={} stats={} stats.unit={}",
        self_prepare_us,
        profstat.timings,
        profstat.unit,
    )
self._line_prof.reset_stats()

It seems like this feature could be useful. The function will need a docstring that describes what it does. It will also be important to add unit tests for the new feature.
