Related issue(s)

Description

Before this PR, the NumericType and ObjectType looked like:

// node.rs
#[derive(Copy, Clone, Debug, PartialEq, Eq, Hash)]
pub enum ObjectType {
    NativeField,
    Boolean,
    Unsigned(u32), //bit size
    Signed(u32),   //bit size
    Pointer(ArrayId),
    Function,
    NotAnObject, //not an object
}

#[derive(Copy, Clone, Debug, PartialEq, Eq)]
pub enum NumericType {
    Signed(u32),
    Unsigned(u32),
    NativeField,
}

Noting that Signed, Unsigned and NativeField were duplicated. This PR deduplicates the structure by doing:

pub enum ObjectType {
    Numeric(NumericType)
    Boolean,
    Pointer(ArrayId),
    Function,
    NotAnObject, //not an object
}
