Want support for more CMIS advertised pages

[bnaecker]

#26 added basic support for decoding the pages a module advertises support for. SFF-8636 modules are pretty simple here, but CMIS is a good deal more complicated. We're parsing a few of the more straightforward pages, but here is a list of some others we should add support for. That requires reading a few more bytes from the module and decoding the right bits. Not complicated, but not critical at this point.

I would like to add the following to the wishlist:

Read page 0x01 byte 142, where bit 5 indicates support for page 0x13 and 0x14, Module Performance Diagnostics Control and Results.

Yeah, that'd be nice. During the racktest whirlwind, we ended up reading lots of data out of those pages, such as the LOS / LOL flags. It'd be very nice to have a high-level decoding command that extracts whatever information is available about the physical layer, things like those LOS flags.
