`rfl::from_generic` (numeric) conversions

[Curve]

Hi there, thanks for the library!

I've stumbled upon an issue when reading from rfl::Generic:

auto generic = rfl::json::read<rfl::Generic>("[10, 10]").value();
auto test    = rfl::from_generic<std::tuple<double, double>>(generic);

This fails with "Could not cast the underlying value to double" - However, it works when immediately doing rfl::json::read without the intermediary rfl::Generic - but does not when using rfl::from_generic.
Is there a special flag that needs to be set to allow the conversion here? I could not find anything on the docs.
