FTP decoder should have Rust port parsers
Feature 2459 and bug 2527 added support for FTP active mode.
That created 2 new functions to process the command lines associated with PORT and EPRT in active mode.
The new functions are
The existing functions for parsing the port number in passive mode have Rust language equivalents. These are:
1. FTPParsePassiveResponseV6 (Rust: rs_ftp_epsv_response)
2. FTPParsePassiveResponse (Rust: rs_ftp_pasv_response)
The new functions should have Rust equivalents for parsing the command line.
