type coercion for arthmetic/binary ops fails for some unsigned/signed mappings

[Omega359]

Describe the bug

The type coercion in the mathematics_numerical_coercion function are too simple and do not properly handle mappings. However, the binary_numeric_coercion function does have the correct coercion rules for numeric values.

To Reproduce

You can see this with the tests:

test_coercion_binary_rule!(
            DataType::Int32,
            DataType::UInt32,
            Operator::Plus,
            DataType::Int32
        );

That is incorrect. Proper expansion of i32 and u32 is i64, not i32.

Expected behavior

Proper numeric type conversion happens when unsigned numeric types are involved.
