Use correct TON and NPI from Jasmin Interceptor

[cypherlou]

Background

I've been compelled to add an mtinterceptor to Jasmin to support a sensitive SMPP gateway. The requirement is broadly to define a TON and NPI as follows;

1. short code with a ton=2 and npi=1
2. long code awith a ton=1 and npi=1
3. text overwrite (alphanumeric source address) with a ton=5 and npi=0

In the last example I have;

    routable.pdu.params['source_addr_ton'] = AddrTon.ALPHANUMERIC
    routable.pdu.params['source_addr_npi'] = AddrNpi.UNKNOWN

The problem

As things stand the TON values defined in smpp/pdu/constants.py (using the NPI as the example), as seen from the Jasmin Interceptor - list(AddrNPI) are;

[
 <AddrNpi.UNKNOWN: 1>
 <AddrNpi.ISDN: 2>,
 <AddrNpi.DATA: 3>,
 <AddrNpi.TELEX: 4>,
 <AddrNpi.LAND_MOBILE: 5>,
 <AddrNpi.NATIONAL: 6>,
 <AddrNpi.PRIVATE: 7>,
 <AddrNpi.ERMES: 8>,
 <AddrNpi.INTERNET: 9>,
 <AddrNpi.WAP_CLIENT_ID: 10>
]

This obviously doesn't match the corresponding values defined in smpp/pdu/constants.py;

addr_npi_name_map = {
    'UNKNOWN': 0x00,
    'ISDN': 0x01,
    'DATA': 0x03,
    'TELEX': 0x04,
    'LAND_MOBILE': 0x06,
    'NATIONAL': 0x08,
    'PRIVATE': 0x09,
    'ERMES': 0x0a,
    'INTERNET': 0x0e,
    'WAP_CLIENT_ID': 0x12,
}

The values (as seen form the Jasmin Interceptor) as defined as the order of the entry in the dict and not the actual value.

I'm getting a rejection pushing my branch;

git push --set-upstream origin 4-use-correct-TON-and-NPI 
remote: Permission to jookies/smpp.pdu.git denied to whorlou.
fatal: unable to access 'https://github.com/jookies/smpp.pdu.git/': The requested URL returned error: 403

My change is pretty simple;
