This commit migrates Value's numeric types to BigInt and BigDecimal. The basic idea is that overflow errors aren't great in a shell environment, and not really necessary. The main immediate consequence is that new errors can occur when serializing Nu values to other formats. You can see this in changes to the various serialization formats (JSON, TOML, etc.). There's a new `CoerceInto` trait that uses the `ToPrimitive` trait from `num_traits` to attempt to coerce a `BigNum` or `BigDecimal` into a target type, and produces a `RangeError` (kind of `ShellError`) if the coercion fails. Another possible future consequence is that certain performance-critical numeric operations might be too slow. If that happens, we can introduce specialized numeric types to help improve the performance of those situations, based on the real-world experience.
