The CBMs are read via unsolicted events for which we register
an event handler.
We don't enable unsolicted events explicitly as this already happens
via the `+CNMI=*,*,2,*,*` whens setting up unsolicted events in
`modem_messaging_enable_unsolicited_events` (ETSI TS 127 005).
This adds support for the Cell Broadcast interface allowing to
receive, list, read and delete Cell Broadcast messages via the
org.freedesktop.ModemManager1.Modem.CellBroadcast and
org.freedesktop.ModemManager1.Cbm interfaces.

This allows to parse the CBMs parameters like channel, part number and
message text. We parse uncompressed GSM7 and UCS2 encodings as
described in 3GPP TS 23.038.

We currently convert to and from the modem's set charset and always pass
'15' as the data coding scheme. Passing the correct data coding scheme
as third argument to CUSD only upsets the network. This contradicts 3GPP
TS 23.038. Other tools like gsm-ussd handle it the same way.
Network responses that require further actions are not yet implemented.
