We were filtering the 4G bands supported by the module when parsing
+UBANDSEL responses, e.g. so that we would not reply unsupported bands
for a given ubandsel value.
But we need the same filtering in 2G and 3G bands, because for example
some modules may support a specific 4G band with a given ubandsel
value, but NOT the associated 3G band. E.g. the TOBY-R200 supports
EUTRAN-4 but not UTRAN-4.
