A quote or an opening bracket is only given special meaning when it is the first character of a value. Brackets and parentheses are treated as ordinary characters for text based values, as nested containers are not possible for these types. Text values are then parsed as before, also when they contain unbalanced brackets, parentheses or quotes.
Items in a tuple are not quoted by the Python client, as the tuple parser does not support quoted strings.
Add unit tests for text values containing separator characters, white space, file paths, numbers, nested containers and 3D vectors.
Lists sent from Python over gRPC are serialized as text, and the list parser split on every comma, also commas inside a string. A category name like "Coal,Calcite" was therefore split in two, and set_discrete_property_category_names() failed with "CategoryValues and CategoryNames must have matching sizes".
The list parser is now quote-aware, and ignores commas inside quoted strings and inside nested brackets and parentheses. A quoted item is parsed as a quoted string also when the surrounding text is unquoted, as is the case for text coming from Python. The Python client quotes and escapes strings in lists and tuples when they contain separator characters.
Add unit tests for the field serialization and a Python test for the category names.
