Refactor and add CMIS mode support #NE-1208 State Done

[loulecrivain]

new user features:

• support for a lot more fields
• SFF8024 identifiers support for module identification
• multi-lane support
• CMIS support with banked pages (tested with finisar optic)
• module reset support (tested with finisar optic)
• module low power request support (tested with finisar optic)
• JSON output

internal additions:

• new strategy architecture to manage different management protocols (SFF8636 and CMIS). module state is represented by object, programming intents are communicated through modification of fields (high-level API).
• documentation on DWDM standards
• tests for INT16 read/write
• page write through binary diff iterator

changes:

• DWDM grid programming overhauled with generic support for all grid modes
• manufacturers can now use / re-use out-of-standard custom pages
• changed default verbosity / logging level to terse

removed:

• deleted old architecture
• deleted old DWDM grid
• dropped high-power mode (since I cannot verify re-implem, we do not have sff8636 c band programmables at hand)

Two nitpicks:

We should run the tests in the CI.
We should not drop high-power mode, even if you cannot verify it at the current point in time.
