Deserializing large serialized Value::Number fails

[niluxv]

Expected behavior: Deserialisation of any serialized struct should succeed.

Actual behavior: When deserializing a large serialized Value::Number an error is returned.

Example:

use ron::value::Value;
let test_var = Value::Number(Number::new(10000000000000000000.0f64));
let test_ser = ron::ser::to_string(&test_var).unwrap();
let test_deser = ron::de::from_str::<Value>(&test_ser);
assert!(test_deser.is_ok()); // <-- this fails

Here test_deser is an Err<Parser(ExpectedInteger, Position { col: 1, line: 1 })>.

Most likely a dupe of #100

I don't think it's an exact duplicate of #100. I'm not trying to deserialize into an integer.
#157 fixes this. Thank you.
