128-bit integers are not supported

[nagisa]

Trying to Config::get a structure that contains u128 fields will fail with an error from serde.

u128 is not supported

---

config-rs should override the u128 and i128 methods to support these integers.

I guess this means that Deserializer::deserialize_u128 and similar functions must be implemented on Value, right? Also, the internal ValueKind type must be able to hold a 128 bit sized integer.

Would you like to implement this in a PR?

[matthiasbeyer]

I just added a patch to config-rs-maint (not in master yet) that adds support for 128bit integers (signed).

Would you like to contribute tests for this patch?

Hi, I'll see if I can make time to contribute some tests. Not super confident I'll be able to, though.
