Move `expect` functions to a separate file This allows tests to test these functions without needing to include the test wrapper directly (now ci/test.lua, formerly test/main.lua). Hopefully this location is also more stable, similar to other libraries that are already tested.

include main test file as a module for testing rewrite main.lua so it can be included as a module rename test.lua to test_test.lua since I plan to rename main.lua to test.lua in a future PR

Set dfhack.internal.IN_TEST flag when running tests

make table_eq check recursive equality and add tests. to write test the table_eq function itself, I expose it in the text env via expect_raw. if we don't want to do this, alternatives could be: 1. add the test to main.lua itself 2. expose the expect.table_eq function via a test_hooks variable. then test.lua could require main.lua and access the function via the hook. may need to update main.lua a bit to ensure it does not run when it is "require"d
