Raw query response support

[Brayden]

Users expect query results from a database to come back in an array of objects, where the objects key is the column name and the value is the database row value. It works great for API responses.

Database GUI's expect results differently, in the case 0 rows are returned but still needs to render column names for example. This pull request aims to include a new route /query/raw that returns the data in a format for GUI's, an example is shown below.

Raw Query

curl --location --request POST 'https://starbasedb.brayden-b8b.workers.dev/query/raw' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer ABC123' \
--data-raw '{
    "sql": "SELECT * FROM artist;",
    "params": []
}'

Response:

{
    "result": {
        "columns": [
            "artistid",
            "artistname"
        ],
        "rows": [
            [
                123,
                "Alice"
            ],
            [
                456,
                "Bob"
            ],

            ]
