High level feedback on terminology: I think we should keep calling the array of schema types "schema", which is the thing that is used by off-chain consumers to know how to interpret the data, and we should find a new name for the "static byte lengths" object used internally by Store and the table libraries. Otherwise it gets confusing if we use "Schema" for one thing onchain and another thing offchain.

Technically no more schema types, just abi types (I wanna ditch the enum and replace it with bytes32 strings that directly mirror config/client).
They can still be called Schema. Or we could rename to something like AbiTypes. getValueAbiTypes getKeyAbiTypes? (doesn't sound as good I guess)

we should find a new name for the "static byte lengths"

Agree, FieldMetadata FieldInfo? This stores the number of fields and their lengths, so FieldLengths wouldn't really work.

do you think these increases in gas are a result of the previous measurements being invalid (because of #1267) or is using constants instead of hardcoded values somehow more expensive?

[dk1a]

dunno, I assume it's #1267, but could be the optimizer being bad too

[alvrs]

code looks good! good to be merged once merge conflicts are resolved
