Implement a mechanism for adding/removing "tags" to/from tensor names, after changes to the tensor

[JeS24]

🐞 What bugs you?

Every Tensor Object has a name parameter, that stores the user-defined (and modifiable) name. After any change is made to the tensor, for example a Lorentz Transform or a Config Change, the name remains unmodified. This may make tracking changes to the tensor difficult for extended calculations.

🎯 Goal

A tag added to the Tensor name, after binary changes are made to the Tensor to mark the respective changes, would be nice to have. For example, after change_config or lorentz_transformation, tags, like "_cc" or "_lt" can be appended/removed.

💡 Possible solutions

Write a helper function for altering name conditionally.

Edit BaseRelativityTensor.lorentz_transform().

Edit change_config() for all Tensors in einsteinpy.symbolic.
