v0.2.0

Release Notes

This is a major release with breaking changes. The codebase has been
written from scratch in Rust and the Python bindings have been updated
to reflect the changes in the underlying implementation.

Changed

• The bc_types argument of CatmullRom class has been renamed to
  bc_type and custom boundary conditions have been removed. The
  available boundary conditions are 'natural', 'closed', and
  'clamped'.
• The smooth_linstring function has been renamed to smooth_linestrings.
  This function now handles a list of LineString geometries instead of a
  single geometry. The code runs in parallel in Rust and is significantly
  faster than the previous implementation. If a single LineString geometry is passed a single LineString geometry is returned, otherwise a list of LineString geometries is returned.
• The compute_tangents has been renamed to linestrings_tangent_angles.
  This function now handles a list of LineString geometries and returns
  the tangent angles at each vertex of the input geometries. The code runs
  in parallel in Rust and is significantly faster than the previous. If a single LineString geometry is passed a single array of tangent angles is returned, otherwise a list of arrays is returned.
