This PR adds lotnum (4-character lot number) to SwitchIdentifiers and exposes ASIC details via swadm (and the dpd-client API). The full lot identifier combines fab, lot, and lotnum (e.g., FTCAK7 instead of just T).

We do keep the current fields separated however, but update the view for the combination.

Adds v1::SwitchIdentifiers for API versions 1-4 (without lotnum), with the latest version (v5+) including the new field.

Fixes #200: Want swadm command to print Tofino ASIC details
Fixes #202: Not reporting full lot numbers in oximeter statistics
