[PATCH] Telit plugin: add load_supported_bands interface

[Carlo Lobrano]

​AT#BND does return the list of supported bands for 2G and UMTS, but for
LTE​ (according to LE910 V2 AT command docs) it is a little bit more
complicated. In fact the LTE bands are represented by a number which is "a
sum of:

1 - B1
2 - B2
4 - B3
8 - B4
...
i - B(2exp(i-1))
...
2147483648 - B32"

So, for example, for a LE910 V2 model that supports like B1, B5, B13 the
value returned by AT#BND will be 2^1+2^5+2^13.
So, in my opinion is really better to take the list of supported bands
directly from the model data sheet.
