Fix/new space engines just dropped

Summarize the changes

Some values have been added to SpaceEngineType in tarantool-module, this change fixes the compilation errors related to that. (And also annoying warnings which show up when building picodata)

• chore: fix compilation warnings

• fix: support tarantool-module v2.0.0

Ensure that

• New code is covered by unit and integration tests.
• Related issues would be automatically closed with gitlab's closing pattern (Closes #1, #2).
• Public modules are documented (check the rendered version with cargo doc --open).
• (if PEST grammar is changed) EBNF grammar reflects these changes (check the result with railroad diagram generator.

Next steps

• Update sbroad submodule in picodata/picodata.
• (if EBNF grammar is changed) create a follow-up issue in picodata/docs.
