[PATCH BlueZ v1 2/2] monitor: Add decoding support for LE Set Host Feature V2

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

Add decoding support for LE Set Host Feature V2 (0x2097) command
which uses a 16-bit bit_number field to support extended LE feature
pages:

< HCI Command: LE Set Host F.. (0x08|0x0097) plen 3
        Bit Number: 32
        Features[0/0][8]:
        00 00 00 00 01 00 00 00                          ........
          Connected Isochronous Stream (Host Support)
        Bit Value: 1
> HCI Event: Command Complete (0x0e) plen 4
      LE Set Host Feature V2 (0x08|0x0097) ncmd 1
        Status: Success (0x00)
