[Request] regex version of "smsc-id" directive in smpp-tlv group

Hi!

There are several groups which contain smsc-id related directives that
allow to use a regex, e.g.:

- in group "smsc" we got "allowed-smsc-id" and the regex version is
"allowed-smsc-id-regex"
- in group "sms-service"" we got "accepted-smsc" and the regex version is
"accepted-smsc-regex"

But in group "smpp-tlv" we only got "smsc-id" and no regex version of the
directive.

Is this something any of you would be willing to add?  :)

Also, shouldn't those directives be standarized?
On one case we got "allowed-smsc-id", on another one "accepted-smsc" and on
the other "smsc-id".
Maybe one of them should be chosen as the standard, and for some time both
ways could be accepted on each group, and then after a while we could
remove the deprecated ones?

Thanks in advance.
