v0.5.3

Added

• Add the Explorer.Series.format/1 function that concatenates multiple series together,
  always returning a string series.

• With the addition of format/1, we also have a new operator for string concatenation
  inside Explorer.Query. It is the <> operator, that is similar to what the Kernel.<>/2
  operator does, but instead of concatenating strings, it concatenates two series, returning
  a string series - it is using format/1 underneath.

• Add support for slicing by series in dataframes and other series.

• Add support for 2D tensors in Explorer.DataFrame.new/2.

Fixed

• Fix Explorer.DataFrame.new/2 to respect the selected dtype when an entire series is nil.

• Improve error message for mismatched dtypes in series operations.

• Fix lazy series operations of binary series and binary values. This is going to wrap binary
  values in the correct dtype, in order to pass down to Polars.

• Fix two bugs in Explorer.DataFrame.pivot_wider/3: nil values in the series that is
  used for new column names is now correctly creating a nil column. We also fixed the problem
  of a duplicated column created after pivoting, and possibly conflicting with an existing
  ID column. We add a suffix for these columns.
