  monitor: Decode Intel DDC LE extended features

The Intel DDC Config Write command (0x3f|0x008b) can carry identifier
0x031f which holds the 248 octet LE extended features array, using the
same layout as LE Read All Local Features: page 0 is 8 octets followed
by 10 pages of 24 octets each.

Decode it with the existing LE feature tables instead of dumping raw
hex, and make the parameter loop stop on truncated/padded entries.

Example, setting only the SCI bits on page 1 (bits 8 and 9):

  hcitool cmd 0x3F 0x008B 0xFA 0x1F 0x03 \
      0xFF 0xF9 0x01 0x3F 0xBE 0x00 0x00 0x80 \
      0x00 0x03 0x00 0x00 ... (padding up to 248 octets)
