Bug in Pyproj Transformer class when using a BoundCRS object (incorrect results)

1

The issue was originally created in the Pyproj issue board, but it was recommended to move it to PROJ. Here is the link to the issue in Pyproj: [https://github.com/pyproj4/pyproj/issues/1467](https://github.com/pyproj4/pyproj/issues/1467) ###...

TransformerGroup does not handle cases where both the allow_superseded and always_xy user arguments is used

### Example code #### Ex. 1 TransformerGroup fails to list up available transformations when specifying both ``always_xy`` and ``allow_superseded `` ```python from pyproj.transformer import TransformerGroup TransformerGroup("EPSG:4230", "EPSG:4326", allow_superseded=True, always_xy=True).transformers ```...

### Example Code showing the issue where the transformation part of the BoundCRS object is ignored ```python from pyproj import CRS,Transformer from pyproj.crs import BoundCRS import numpy as np np.set_printoptions(suppress=True)...

The ``TransformerGroup`` class in Pyproj does not manage to return the same list of available transformations between two CRSs as `the `projinfo`` command in the PROJ CLI. Ideally they should...

Add source_epoch and target_epoch parameters to ``Transformer.from_crs()`` and ``TransformerGroup``, matching the --s_epoch and --t_epoch options in ``cs2cs`` in PROJ.

#### Background Add source_epoch and target_epoch parameters to ``Transformer.from_crs()`` and ``TransformerGroup``, matching the --s_epoch and --t_epoch options in ``cs2cs`` in PROJ. Dynamic reference frames such as **ITRF**, **NAD83(CSRS)**, **ETRF**, and...

Add a .devcontainer configuration to the repository so contributors can easily spin up a ready-to-code environment using GitHub Codespaces or VS Code Dev Containers. Setting up the development environment manually...
