-------------------
* Added
- New module ``crawlytics`` for analyzing crawl DataFrames. Includes functions to
analyze crawl DataFrames (``images``, ``redirects``, and ``links``), as well as
functions to handle large files (``jl_to_parquet``, ``jl_subset``, ``parquet_columns``).
- New ``encoding`` option for ``logs_to_df``.
- Option to save the output of ``url_to_df`` to a parquet file.
* Changed
- Remove requirement to delete existing log output and error files if they exist.
The function will now overwrite them if they do.
- Autothrottling is enabled by default in ``crawl_headers`` to minimize being blocked.
* Fixed
- Always get absolute path for img src while crawling.
- Handle NA src attributes when extracting images.
- Change fillna(method="ffill") to ffill for ``url_to_df``.
