ensure output col names from snowflake are of same case as the malloy identifiers
snowflake connection and executor tests succeed now
add support for safe cast
ensure safe cast expr test passes for snowflake

In Snowflake: by default even if we have quotes it seems to have ALL_CAPS in output

but explicitly saying please do not ignore case (which is what we decided for malloy) outputs match expected outputs (in terms of case)
