reticulate 1.43.0

• Fixed usage of micromamba and mamba, next-generation conda environment management tools.
  reticulate now prefers to use micromamba, mamba, then conda when managing environments (@gdevenyi, #1771).

• Added str(), dim(), and t() S3 methods for NumPy Arrays.

• Fixed a segfault observed on R session exit (#1785, #1786).

• Added check in install_miniconda() if existing files will be overwritten. (#1794, #1796)

• Fixed error in install_python() under R 4.5 when the requested Python
  version has a ":latest" suffix, as it does by default. (#1792, #1797)

• Fixed error in get_python_conda_info() when conda not found through conda-meta/history
  and NULL is passed to normalizePath (#1184)

• Hotfix to pin uv version resolved by reticulate to <0.8.0. (#1812)

• Python discovery by uv is much faster now. The internal utility uv_python_list()
  searches only for managed python environments by default. Users can request discovery of
  system pythons by setting UV_PYTHON_PREFERENCE. Also, uv_python_list() will now discover
  pyenv pythons and python binaries installed by install_python() if a system python is requested. (#1810)
