Duplicated table entries

Hi @DomCR , I hope you are doing well.
I'm currently reading a DXF file using your library. An exception occurred when reading some of my sample files.
Here is a snippet of my sample.

The layer "RESC_ART" appears multiple times. When the library continues reading and attempts to add the next layer, it throws a "duplicate key 'RESC_ART'" error, as shown below.

My question is: Should the later layers overwrite the previous ones, or is there a better solution?

I'm not very familiar with this field, so I appreciate your patience as I try to understand things.
Thank you!

Allow to add the last entry with the same name if the Failsafe flag is on and notify the user as an Error.

The resolution of this issue may cause some information lose due that if the last entry doesn't have the links to other objects like dictionaries or entities those will not be linked or even added to the document.
