dms: new 'Extended LTE Band Capability' TLV in "Get Band Capabilities"
The 'LTE Band Capability' TLV (0x10) is a 64-bit mask, and therefore
isn't capable of reporting more than 64 bands (1 to 64).
In order to support LTE bands greater than 64, this new 'extended' TLV
is defined, as an array of uint16 values, one per band.
E.g. this "Get Band Capabilities" response where the modem reports
band 66:
