Integer values above the 32 bit limit cause faulty generated code.

Hi,

I am using this ASN.1 spec:

Test DEFINITIONS AUTOMATIC TAGS ::=

BEGIN

maxofRICrequestID INTEGER ::= 4294967295

END

This is an ASN.1 definition pulled from E2AP.

rasn generates the following code for this:

#[allow(
    non_camel_case_types,
    non_snake_case,
    non_upper_case_globals,
    unused,
    clippy::too_many_arguments
)]
pub mod test {
    extern crate alloc;
    use core::borrow::Borrow;
    use rasn::prelude::*;
    use std::sync::LazyLock;
    pub static MAXOF_RICREQUEST_ID: LazyLock<Integer> = LazyLock::new(|| Integer::from(4294967295));
}

If you try to compile this, you'll get this error:

error: literal out of range for `i32`
  --> test-example/src/test.rs:13:88
   |
13 |     pub static MAXOF_RICREQUEST_ID: LazyLock<Integer> = LazyLock::new(|| Integer::from(4294967295));
   |                                                                                        ^^^^^^^^^^
   |
   = note: the literal `4294967295` does not fit into the type `i32` whose range is `-2147483648..=2147483647`
   = help: consider using the type `u32` instead
   = note: `#[deny(overflowing_literals)]` on by default

The solution I have been using is to change:

pub static MAXOF_RICREQUEST_ID: LazyLock<Integer> = LazyLock::new(|| Integer::from(4294967295));

to:

pub static MAXOF_RICREQUEST_ID: LazyLock<Integer> = LazyLock::new(|| Integer::from(4294967295u128));

Can the compiler be changed to account for values equal to or greater than unsigned 32 bit max?
