feat: Add AFTN message parsing functionality

This commit adds functionality to parse AFTN messages in the `aftn_parser.go` file. The `Parse` method now correctly parses the message based on its type and extracts the relevant data. Additionally, the `FindPatterns` and `ParseBody` functions have been updated to remove the dependency on the `config` package and instead use the `config.GetBodyPatterns` function to retrieve the body patterns. This change improves the modularity and maintainability of the code.

Note: This commit message assumes that the `config` package has been refactored to use the `GetBodyPatterns` function.
