fix removal of consecutive tranposes with branches

[jicampos]

This PR adds logic to handle and remove consecutive Transpose operations with branches. Originally, the package only removed consecutive Transpose operations when no branches were involved.

• Added a check to ensure correct removal of redundant Transpose nodes without affecting graph structure in RemoveConsecutiveChanFirstAndChanLastTrafos.
• Additionally, a check has been added to prevent redundant Transpose operations in MoveChanFirstDownstream when handling forked branches in the graph.
