v0.10.0

BREAKING CHANGES DUE TO RUST-POLARS UPDATE

• rust-polars is updated to 2023-10-25 unreleased version (#442)
  • New subnamespace "name" that contains methods $prefix(), $suffix()
keep() (renamed from keep_name()) and map() (renamed from map_alias()).
  • $dt$round() gains an argument ambiguous.
  • The following methods now accept an Expr as input: $top_k(), $bottom_k(),
    $list$join(), $str$strip_chars(), $str$strip_chars_start(),
    $str$strip_chars_end(), $str$split_exact().
  • The following methods were renamed:
    • $str$n_chars() -> $str$len_chars()
    • $str$lengths() -> $str$len_bytes()
    • $str$ljust() -> $str$pad_end()
    • $str$rjust() -> $str$pad_start()
  • $concat() with how = "diagonal" now accepts an argument to_supertypes
    to automatically convert concatenated columns to the same type.
  • pl$enable_string_cache() doesn't take any argument anymore. The string cache
    can now be disabled with pl$disable_string_cache().
  • $scan_parquet() gains an argument hive_partitioning.
  • $meta$tree_format() has a better formatted output.

Breaking changes

• $scan_csv() and $read_csv() now match more closely the Python-Polars API (#455):
  • sep is renamed separator, overwrite_dtypes is renamed dtypes,
    parse_dates is renamed try_parse_dates.
  • new arguments rechunk, eol_char, raise_if_empty, truncate_ragged_lines
  • path can now be a vector of characters indicating several paths to CSV files.
    This only works if all CSV files have the same schema.

What's changed

• New class RPolarsSQLContext and its methods to perform SQL queries on DataFrame-
  like objects. To use this feature, needs to build Rust library with full features
  (#457).
• New methods $peak_min() and $peak_max() to find local minima and maxima in
  an Expr (#462).
• New methods $read_ndjson() and $scan_ndjson() (#471).
• New method $with_context() for LazyFrame to have access to columns from
  other Data/LazyFrames during the computation.
