Roslyn Source generators are not supposed to access I/O. To get around this we have to use `AdditionalFiles` to give the analyzer access to read/load the schema files. To write the schema files we have to use a separate program altogether. - [X] Adds SerializationSchemaGenerator - [X] Splits out the SerializationGenerator code
