Integers that don't fit into u32 get silently mapped to null

[dbdr]

I think the issue is here:

firestore-db-and-auth-rs/src/firebase_rest_to_rust.rs

Line 31 in e8fd526

if let Ok(four) = integer_value.parse::<u32>() {

The u32 type is indeed wrong. The documentation[1] defines i64 as integer type.
