bip/smpp2sim: TERMINAL PROFILE that matches what we do

pySim-smpp2sim sends "ff" * 32, that byte list tells every card the
terminal has a display, a keypad, a second card slot, a radio it can
query for location and NMR, five BIP bearers and six transport modes and
a toaster and a dog according to TS 102 223 5.2

We only have the twelfth byte and one bit of the seventeenth and no dog.

A card issues annoying weird things like PROVIDE LOCAL INFORMATION or
UDP only because the profile said so, so stop pretending we know what any
of that is.

Annex T table T.1 lists what a Connected Entity (a CAT client that is not
the modem) may announce. Announce that and the SMS-PP download and
SEND SHORT MESSAGE bits the OTA path needs, only the bearer is obviously
made up, it's the host TCP stack and 5.2 closest match is GPRS.

We can still extend and change all of this, but for now something that
works and constrains what the card asks for and is therefore actually
reproducible is important.
