`MessageTypeParser.parseMessageType()` Fails to Parse Valid Parquet Schemas with Special Characters in Field Names

### Describe the bug, including details regarding any error messages, version, and platform.

The MessageTypeParser.parseMessageType(String) method fails when parsing Parquet schemas containing field names with special characters such as "name=id" or "first name". These field names are valid in Parquet schema definitions and Parquet files successfully support them. However, parseMessageType throws an error or fails to deserialize such schemas back into a valid MessageType object.

Steps to Reproduce:
Create a valid Parquet schema with a field name like name=id or first name.
Convert it to a string using .toString().
Attempt to parse it back using MessageTypeParser.parseMessageType(parquetSchema.toString()).

Suggested Fix:
Enhance MessageTypeParser to properly handle and deserialize field names containing special characters, ensuring compliance with the Parquet specification.

### Component(s)

_No response_

Comienza con MessageTypeParser.parseMessageType(String) y reproduce el recorrido de ida y vuelta usando un esquema Parquet válido cuyo nombre de campo contenga "name=id" o "first name". Se considera terminado cuando la cadena de esquema producida por toString() se analiza de nuevo como un MessageType válido equivalente sin errores.
