Add JSON protocol schema 8, which is similar in semantic concept to json
protocol schema 7 but
- Requires user specification of the schema for the command List
This allows json protocols to switch which commands they're interning
without requiring further bumps to the protocol schema
- Does the same thing for command annotations, liquids, and labware
For the same reasons.

This should be a big step forward in flexibility for our protocol schemas.
