DeepLClient.get_multilingual_glossary_entries method returns entries as TSV string instead of dict

[jones-liam-j]

Both the readme and the type hinting suggest that the entries property of MultilingualGlossaryDictionaryEntries should return a dictionary, but instead they return a tab-separated string.

E.g. instead of:

{"red":"rojo", "blue": "azul", "green": "verde"}

the result is:

"red\trojo\nblue\t\azul\ngreen\tverde"
