Allows generating functions equivalent to the read_process_xy_records functions in this crate for your own types. This is rather a workaround because the generic approach (read_process_records_init) does currently not work.

• $format: String specifying the name of the sequence format (for genrated documentation)
• $name: name of the generated function
• $name_init: name of another generated function, which takes a closure initializing the readers in the background thread.
• $RecordSet: record set type (see RecordSetReader::RecordSet). In addition to the trait requirements, &$RecordSet needs to implement IntoIterator<Item=$Record>.
• $Record: record type returned by the record set iterator.
• $Error: reading error type (RecordSetReader::Err)
